Here are some of the new classes in Java that i learnt and used in my game program..

ArrayList<type>

Functionality : It is similar to Array but this ArrayList comes with inbuilt functions/methods..

Usage : ArrayList<String> quotes = new ArrayList<String>

Inbuilt Methods are :

add(object element) – This will adds the new element to the list of array

-     ex: quotes.add(“everyday we will be learning new things.. even if we win or lose”);

remove(int index) – This will remove the object at the given index

remove(object element) - This will remove the element from the array list

contains(object element) - returns the value true if the array list has the object mentioned

isEmpty() – Returns true if the array list is empty

indexOf(Object element) – returns index of object in the array list

size() – will returns the size of the array list

get(int Index) – returns the value @ mentioned Index in the Array list

concat(String)

Functionality : It will concat the string inside the baces

usage : String temp = “where”;

-               String full = temp.concat(” are you now??”);

-               full will be holding full = “where are you now??”

Integer.toString(int)

Functionality : It will convert the Integer to String

Usage : String x = Integer.toString(3);

For More Classes and packages make sure that you visit or refer this site http://download.oracle.com/javase/1,5.0/docs/api/

Functionality : it will covert the input String to Integer. It will only for the ASCII values (0 to 9). if any other value is given like “THREE” it will give error at run time.

Here, Integer -> is a Class

-           parseInt() -> is a method/funtional call inside the class Integer, which will take String as the input and returns the Int Value

usage :              int x = Integer.parseInt(“45″);

-

for(<datatype> <variable_name> : <array_variable_name>)

How It Works: <variable_name> will hold the value(content) of the array which is given after the “:” symbol. it will start form the first value of the array. once the end of the array is reached it will break (same break; statement from C) form the for loop.

Here, <datatype> -> is the datatype of the array.

-          <variable_name> -> name of the local variable, which will hold the value of the array. This variable can be used inside the for loop.

-          <array_variable_name> -> the array which has been declared and whose values you want to use inside the loop.

Usage :  for(int x : lucky_numbers)

-                 lucky_numbers is the array holding the lucky numbers. it is a int array.

-                 int[] lucky_numbers = new int[7]; // here the array size is of 7.. hence the for loop will execute 7 times

-                 in first loop x will have the value lucky_numbers[0].  in second loop it will have lucky_numbers[1]  and so on.. once it reaches lucky_number[6] for the next looping it will break from the for loop.

Note: There is also for(intialize; condition_check; operation) kind of for loop in java ex: for(int i = 0; i<10; i++)

-

Math.random()

Functionality : This will generates the random number for 0 to just less than 1. The return value of this is double. So we need to typecast it to the datatype that we want.

Usage : <datatype> <variable_name> = (<datatype>) Math.random();

-                here if we give the datatype as int or long or short or byte the variable will be get the value 0. Because the Math.random() generates the number 0 to 0.999999999999999999999999999999999999999999 (double value). If we want a random number between 0 to 8 then we have to use the above function as:

-                  int ran_num = (int) (Math.random() * 8); //this will generate the random number between 0 to 8.

-

-> For the int[], to find out the length of the array you just have to mention <array_name>.length, but for String to find out the length you have to give <string_name>.length()

-

How to get input from user:

import java.io.* -> will imports all the necessary java inbuilt classes for I/O interface.

import java.io.*;

class Input_User
{
	public String GetUserInput()
	{
		String lineInput = null;

		try
		{
			BufferedReader is = new BufferedReader(new InputStreamReader(System.in));
			lineInput = is.readLine();
			if(lineInput.length() == 0)
				return null;
		}
		catch(IOException e)
		{
			System.out.println("IOExeption " + e);
		}

		return lineInput;
	}
}

Input_User -> is just a class name. any name can be given.

GetUserInput -> is just a method inside the class Input_User which will return a String.

Hmmm.. Leaving CAT and IIM thing apart, these are the things which I learnt in Class :

-> In one file we can have only one public class.
-> creating the instances of the class doesnot mean that Object is created and memory is allocated. For each instances you should create object.
   ex :
		class dog
		{
			String name;
			int Size;

			public void bark()
			{
				System.out.println("Bow wow.");
			}
		}

		class animals
		{
			dog d1;
			dog d2;
			dog d3;

			public void action()
			{
				//code for action for each dog;
			}
		}

		-> here Notice that in class animals, 3 instances of class has been created. But memory is not allocated. hence the Object d1, d2 and d3 are not created.
		   So, we have to create object for each class like
		   <instance> = new <class_name>();
		   for the above example in class animal we have to create object like,

		class animals
		{
			dog d1;
			dog d2;
			dog d3;

			d1 = new dog();
			d2 = new dog();
			d3 = new dog();

			public void action()
			{
				//code for action for each dog;
			}
		}

		-> Better thing is. as soon as you create the instance of the class create the object too.. like for the above example,
		class animals
		{
			dog d1 = new dog();
			dog d2 = new dog();
			dog d3 = new dog();

			public void action()
			{
				//code for action for each dog;
			}
		}

-> When there is a Method inside the class, make sure that it is called atleast once.. else the what you wanted to do will never happen.
   for the above example, just by creating the object dog, the methos/ funtion inside the class dog will not execute. in simple words, d1, d2 and d3 dogs will never bark.
   If you want d1, d2 and d3 dogs to bark, all you have to do is call the method or function in class animals.

   class animals
		{
			dog d1 = new dog();
			dog d2 = new dog();
			dog d3 = new dog();

			public void action()
			{
				d1.bark();
				d2.bark();
				d3.bark();
			}
		}

-> you will nt be able to define a method inside the public static void main(String[] args).. as we all know we can call one function from another.. we can't define it inside other..

Just before my vacation started,  thirst for Java increased.. I thought of joining course.. I asked few of my F.R.I.E.N.D.S for a good book.. Indeed one of my F.R.I.E.N.D gave me a nice advice.. “learn yourself.. No one is better tutor for you than yourself” – Vikram(one of my BEST F.R.I.E.N.D.. I always think that he is my GURU).. Another F.R.I.E.N.D of mine suggested book “Head First Java“.. Well structured book indeed.. and very good for beginners..

Well, I Downloaded the e-book and started learning.. Authors have written the book in very different way.. Rather than boring you about all the theories, authors have written it in very experimental way.. Many pictures are present in the book which will explain us what we are reading in this page.. After all our mind can grasp more thing if there are some pitures of what we are reading.. ..

Just open the book.. you will understand what i meat..

Between here are the lesson that i learnt on my First day:

• First thing is to install the JAVA SDK.. download the latest version from the below link : http://www.oracle.com/technetwork/java/javase/downloads/index.html
• Make sure that you have edited the Environmental variable PATH. path should be bin folder where your  javac.exe  and java.exe present
• In Command prompt, go to the path where you have saved your code as <filename>.java
• now type “javac <filename>.java“

There are 3 things which you need for working as a android developer/programmer.

1. Java
2. Android SDK kit
3. Eclipse. (This one you don’t have to install it you just have to run the eclipse manager)

Here are the lists of problems which I faced while installing the Android:

-> First check whether your windows is 64 bit or 32 bit from “My Computer” properties. Because you have to install the same version of Java.

-> If you are using the windows 7 of 64 bit then remember one thing, all the 64 bit softwares will be installed in “Program Files”. If the softwares are of 32 bit then it will be installed under “Program Files (x86)”

-> Then to download 64 bit Java you need 64 bit browser otherwise all the softwares you install will be 32 bit. First check whether your browser is 64 bit (help-> about browser).

-> If are opening the IE then go to Program Files -> iexplorer -> iexplorer.exe else download the 64 bit browser and install. NOTE: Google Chrome browser will not be able to download the 64 bit JAVA. Even if you download it will be 32 bit.

-> Download Java 64 bit and install the same.

-> After installation go to command prompt and type ‘java’. It should not give any errors. If it is throwing any error then go to the bin folder path inside the path where u have installed Java then type ‘java’. If it is working fine there then there is a problem with the path. Else there is a problem with the installation.

Note: path will be C://Program Files/Java/Jre/bin

-> If there is a problem with path, then go to environmental variables, create a new environmental variable with the path “java-> jre->bin” folder. Then open the command prompt again or go the default path in the command prompt and then type ‘java’. There should not be any error. If no errors then your Java installation is done.

-> Now download the Android SDK kit and install the sdkManage.exe for 64 bit.

-> Then download the Eclipse for 64 bit.

-> Then just run the eclipse.exe.

-> Help -> install new software and then install the ADT (Android Development Tools). It is a plugin for the eclipse to run the Android Programs.

-> Then in eclipse under Windows -> preference select the Android and give the sdkManager.exe folder path.

-> Create the Virtual device for your android program to run and then start using the working in Android programming.

-> To create the new project new -> project. Create an android project. Then start working. Refer android reference from web to understand easily at the beginning.

Hippo got us blazers for us since there was a dress code at BGC. It was the first time in my life where I went to a club for the celebration of New Year. It was new to all of us except Hippo, Viju and Reebok. I was very much excited about the coming year 2010. At 10:30 PM we started dancing to the music. It was not that great song but the last few minutes of year 2009 made it very special. Countdown started…. 10, 9, 8, ……… 2, 1.. HAPPY NEW YEAR. Everyone started greeting each other for the year 2010. We started dancing again, and it was 1:50 AM when we left BGC. Next day we went to office. And we greeted all our F.R.I.E.N.D.S who couldn’t make it to BGC.

In Jan 2010 I was supposed to go to onsite but because of the project closure it got cancelled. However, I enjoyed myself in 2 trips, Wayanad and Kodaikenal. Both trips added colours to my life. It was here that my relations were elevated to a higher level. I got more close to my F.R.I.E.N.D.S. I also got a chance to know my colleagues as F.R.I.E.N.D.S. As time passed, Feb came. I was then moved to another team which made me a little upset. Somehow I consoled myself till March when again my team was changed, this time to a new domain. I started as a fresher. I was not at all happy with the work I was doing. The only day enjoyed in this month was that on my birthday went great. Thanks to all my F.R.I.E.N.D.S for being with me at that time. By the time it was April I started preparing my resume and kept my eyes open for new jobs. During the next few months I gave around 3 interviews. First one went horrible, second interview was ok and third, though for a different domain, went awesome. The best part was I got rejected in all the three.  May and June is the month of birthday parties and we had some awesome ones as well. However, even though we were enjoying these parties, there was something somewhere in our heart whispering to us that all this might end soon as many of my F.R.I.E.N.D.S were leaving either for short term or long. And that whisper became loud enough when in June mid Ninja went to Germany for 3 months and we heard plans of Chenna and Rakshith quitting as well. The only solace was the news that I will be called back to my old domain with a new project. To remember the good times, we had a Pondi trip in the month of July. We thought it was the best trip among all the trips but by the end of the year 2010 we realised that it was the worst of all as many rumours started coming about the people we loved and liked the most (including me). Soon after the trip, 2 of our F.R.I.E.N.D.S Reebok and Chenna left work and went for higher studies. In the Month of August I went back to old team with new project and I started giving training to teammates and mentored freshers. It was here what I learnt from March till July as a fresher paid me off. From September till December there were more changes to come. Hippo left office for another job, Benne went to Germany, Deva went to Japan, Justin and Lakshmi Shama K went to Germany. Meanwhile, Ninja came back and was with us for a short time when he went to support a different project at a different location. Now only 5 of us Shiva, Ambi, Sandy, Viju and me in the breakfast and lunch group, and in total 8 of us including  Koli, Panda and Chummi. My life was moving towards greener side of the hill. I was enjoying mentoring new joinees and was conducting interviews. In the month of November I heard that I will be going for Germany on 11^th of Jan 2011 for 6 months. In December my roommate, Deva, Justin and Lakshmi Shama K came back from their onsite. And we heard that Sandy will be going to Japan in Feb 2011. I thought of celebrating coming year 2011 with a trip. But it was cancelled as no one was willing to come. A few of us started planning for the celebration of 2011. To make myself available at that time, I rescheduled my visit to native. I went a week early and came back. Finally the “D day” arrived. It was Dec 31^st.Last day of the year 2010. And guess what?. The plans as usual were cancelled. I got upset because I cancelled my plan of visiting native for celebrating New Year 2011 with my F.R.I.E.N.D.S. I stayed late in office and came back home with a sad face.

I saw many ups and down in the year 2010, 1) my career, in the beginning it started of very bad but at the end it started growing well. 2) Personal life, in the beginning I was getting to know my F.R.I.E.N.D.S very closely, I was getting to gain good F.R.I.E.N.D.Ship with all my F.R.I.E.N.D.S. But at the end I started to lose someone’s trust who was very close to me from mid-2009 and hence closeness started to fade out in my memories. I hope new relations will be formed and old relationships will be mended in 2011. However there was one thing which has remained constant ever, no girlfriend in 2009 and even now.

Hmmm, Life is all about this, “Facing new problems, facing new people and having fun in the middle. Sometimes we get very close to some of our F.R.I.E.N.D.S and find happiness in helping them when they are in need and sharing our good or bad moments”.

@year 2010: you were a wonderful year to me. I can never forget you in my life. You gave me close F.R.I.E.N.D.S and good career too. I was very sad to say good bye to you. But I was forced to. I hope your brother 2011 will bring me at least half of the happiness that you bought me.

Bye Bye year 2010. You are a very special chapter in my life.

Come on u can do it.. u have done it before.. and u taught your hostel friends.. which move was that?? Oh shit, what the Fun man!! come on.. come on..

I tasted one thing that, how a person can feel, how much he gets disturbed when he try to do his best practice and he forgot one small part of the routine while doing it after a very long time.. It is so difficult to digest.. And I also tasted one more thing that, how happy the same person can be, when he finds out or remember what he forgot..

So F.R.I.E.N.D.S, when you are good at something, do not stop practicing the same. You will find it very difficult to digest if you made one wrong move or if you forget a part of your best practice when you try to do it after a very long time. Keep practicing at regular intervals.. Practice Makes a man/ a woman perfect..

That Sunday started with a joke but never thought tat it would end like the way it ended.

After her call I talked to my friend Chaitra who wanted to know about the projects in final year of engineering. She was so much worried about it now even before she has completed her 5th sem. i said not to worry about that so much and I’ll drop by at her place when I go back to native next month and inform her what all can be done for a project (guys only to discuss about the project). I was still on bed when I was talking to her. When she hung up I checked the time it was 1:00 PM. still not in a mood to get off my bed.

I heard the door bell, so I got off my bed to check who that was. Ranjith, guy studying in 9th class, my neighbor. He was here to play the commandos game. I turned on the computer and started doing the regular morning chores in the afternoon. (It is very hard to change the usual routines for Sundays ).

I had nothing from the morning and I had only bread and jam for the day. I was lazy to go out have food and come home. So I started with bread and Jam while Ranjith was playing Commandos 1. I eat 6 bread pieces and my stomach was full. I asked him leave the computer to me since he was finding it very difficult to continue. I could help him finishing that first level. He let me to play and I liked commandos 3 so I continued Commandos 3 from where I left yesterday. It took so long to come to end but I sucked at the end. Instead of clicking Quickload I clicked Quicksave.

I left him to play and started reading 2 states. I got bored in the middle. I had planned to check where the GYM was located so that I can go for the GYM classes. I asked him to come with me since he knew where it was. After that I remembered that I had to visit Dinner aunty to know what had happened, but she was not there at home. So I had no choice but to have dinner outside. I came back home with a huge disappointment since gym was closed and dinner aunty was not there at her home.

To brighten up, I thought of watching F.R.I.E.N.D.S. I turned on my comp and clicked on season 2 – one with the breast milk episode. It is really a mind refreshing Episode. I liked the sequence where Joey and Chandler ask Carol about the breast feeding. In the end the question from Joey, “hey I got one, I got one. If he (he = BEN, Ross, Carol and Susan’s only son) blows into one, does the other one get bigger??” was humorous.. ha ha. My phone started ringing when Joey was having problem with that new Hombre guy. For the first time in his life he lost a girl for the Cow boy suit that hombre guy was wearing. I looked at the phone to know who is calling; it showed “Mallya 23 July”. Wow!! I was scared to pick up the call and talk to him. I was feeling guilty about what had happened in the past between me and him. I didn’t answer. And after the call got cut I kept my phone in silent mode and switched off the vibration in silent mode too. That was it I couldn’t enjoy that F.R.I.E.N.D.S episode anymore. I went and had dinner and when I came back home there were 2 missed calls from the same guy. Ok now I thought what do I do? I heard a voice “Do not hate anyone; be neutral, everything will be fine“. That was from my roommate Benne. We talked about that long back. I realized what my roommate meant, when he was at his native and after I got call from Mallya. Actually tat “be neutral” thing I heard it from 2 of my other friends too. Ambi and chenna. Just 2 or 3 days back. Ok, I thought what big deal, I can be neutral, and I can face this, come-on. I dared to call him. Luckily his line was busy. I felt happy and I sat down to start ironing my cloths. Clock showed 8:55 PM.

It was 11:35 PM. I finally ironed all my clothes so that I don’t have to Iron for another month. :0 I checked my mobile there were again 2 missed calls from Mallya and 4 or 5 messages from others. I ignored his missed calls and checked all messages. After reading sandy’s message I felt happy, coz she was supposed to bring Akki roti as promised by her the following day but because of timing problem she promised to get next to next day that is Tuesday. I was happy because at least I will be having Akki roti from home after a long time.

I wrote a testimonial to Ambi and asked her to check whether it was good. She said for reading it was good but it won’t picture her in a good way. So I modified that a little and corrected the mistakes (which were very few ). It was 11:58 PM by that time. I switched off computer.

I thought of watching the next episode of F.R.I.E.N.D.S. the one where Heckles Dies. I switched on the computer and I enjoyed that episode. I was thinking what to reply to that guy. It is funny that our feelings change in different ways at different time. I was so close to him during engineering days and now I can’t face him face to face. I thought let me leave these worrying thoughts behind and face that tomorrow morning, now it’s a sleeping time. I switched off the computer again and I got back to Bed. It was already past 12:30 AM.

There is nothing like that. Just read the complete blog you will find out what it means..

Hmmm, it is Friday night, you are very eagerly waiting for the weekend and are quite excited about it. You are dreaming about the “FUN ” that you are gonna have tomorrow….. suddenly you hear a tttrrrrrriing…. its that of the alarm…… hurray it is Saturday….. Morning is very beautiful ….. You waited for this day from the last 5 working days….. You get ready as soon as possible to see your F.R.I.E.N.D.S and you are on your way to “ADDA” by walk…… You and your friends  plan something to make your weekend colorful. Everything goes according to your plan BUT…….

“Anna, appa…. dharma needi tande…..”

You see a  poor, physically disabled person. . He is an old senile person probably elder than your Grandfather(may be !!!) He being very weak to even get up and walk by himself,  is sitting like that and repeating the same words for each and every person passing by…. Instinctively,  something hurts you from inside.  ”CHE  PAAPA” are the only 2 words that finally manage to come out of your mouth…. You dont want that sight to ruin your weekend. Still,the sight keeps haunting your mind. It asks you thousands of questions – Who are they??? why are they like that ?? what made them so?? why is our government ineffective in taking care of them??  There are many Ashramas in the city to take care of such people. Still why do we find so many people lying on the street unattended?? Why???

In my point of view , to have a nice weekend even after seeing such a sight is possible only in 2 ways. 1. You should not be sensitive and should have a  ”don’t care” attitude for such people.  2. Euthanasia  should be legalized to avoid such sights !!!

Euthanasia is a Greek word meaning “Good death”. It is a practice of ending life in a painless manner i.e.  in 2 words “Mercy killing”. Imagine, if “Euthanasia” is legal in India. How it would have been?? …. I have seen many families who are having parents or children who are ill and  whose illness cannot be cured by any doctor. They are just a source of leakage of all the income that each person in that family is earning. Their illness cannot be cured and family status will also go down as clock ticks in terms of year. There should always be one person to look after that poor ill person. We would feel that there is no happiness for the care-taker till that ill person dies.  Have you thought about what will be going on in that ill person’s mind?? Consider you are that person, and you cannot speak, your son/ daughter/ wife/ husband is looking after you…. Everyday day they are spending money on you in hospital even they know it cant be cured. do you want him/ her not to be happy until you die?? just think about it. However, the care-taker loves that other person very much and would not even think of death as a remedy to the ill person. This is the love on which humanity still exists.  Euthanasia is an option only if the person is suffering too much and is not able to tolerate the pain.

Guys, I dont know the Pros and Cons of legalizing “Euthanasia” . Some people might misuse it . But for some people it might be a gift.

Hmmm, to end that weekend story…. i think  if mercy killing is legalized your weekend would be exactly as you planned.

After reading this, please do comment about your opinion on Euthanasia.

“Every opinion counts”.

You wont be killed mercilessly for giving opinions.
