The code only worked after a modifying the place of [] in the Class.
// A program to print some text.public class Welcome

// main method begins execution of Java application
public static void main( String [] args )

System.out.println(“Hello World!”);
System.out.println( “Welcome to Java Programming! on Ubuntu 10.04″ );

Thanks Mr. Prakash for your valuable comment.
is that all or do i need to setup the the environment variables?
thanks
If you will install it from package manager, then I don’t think that it’s necessary ..if so then just open .bashrc from your home directory and add the path where you have installed the JDK.
santosh@santosh-laptop:~$ sudo apt-get install openjdk-6-jdk
E: Could not get lock /var/lib/dpkg/lock – open (11: Resource temporarily unavailable)
E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?
Tell me how to handle above error ?
You need to make sure that “no other installation or un-installation is going on”. If no other installation or un-installation is going on and the error shows up, then possibly some installation is stuck in you system when you were trying to install something in the past.
Now try this command:
sudo apt-get update
After this try installing open-jdk again.
