Article involves,how to steps to install the java on Linux and execute the java application on Linux:-

Part I:

Install J2SE, JDK On Linux:-

Rather than Rpm packages,BIN gives you more control over how and where you want to have your Java-environment installed.
Get download the latest version of jdk ,Bin ,like java_ee_sdk-5_01-linux.bin from java.sun.com/download.html.

Now lets start with the installation of java on linux platform by changing the file permissions as 755(to get start with installation make sure you are appear as root user).

Change the file permissions:-
[root@localhost:~]# chmod 755 java_ee_sdk-5_01-linux.bin

Changing the file permissions of java_ee_sdk-5_01-linux.bin as 755

Change the path of directory:-
[root@localhost:~#]cd /usr/local/java

it's nice to always have JDK installed in /usr/local/jdk, But still you want to install it any other then you can install it just by changing the directory.

Run the self exracting binary:-
[root@localhost: java/#]./ java_ee_sdk-5_01-linux.bin

The license agreement is displayed. Review the agreement. Press the space bar to display the next page. At the end, enter yes to proceed with the installation.

Now Jdk been install on /usr/local/java.

Part II

Execution of java application on Linux platform:-

Lets test.java be our java application and be sure, /usr/local/java be your current working directory.

[root@localhost:/java]$javac test.java

This interpreter takes your byte code file and carries out the instructions by translating them into instructions that your computer can understand.

Now the compilation of your application be done and class file of name test.class be created(test.class is in the byte code format)

[root@localhost:/java]$java test

And here is the execution of your application, now you can see the output of your application...
