    public void main() {

System.out.println("Hello world!");
    }

}

This is the first time I am using eclipse and I wanted to see what it is like. I am using ubuntu 12.04 with java-6-openjdk-i386

You need to use:

public static void main(String[] args) {
    System.out.println("Hello world!"); 
}

Or equivalently:

public static void main(String... args) {
    System.out.println("Hello world!"); 
}
