{

public static void main(String a[])

{

System.out.println("Hello World");

}

}

above is the java program. java is an Object Oriented Language. I want to know what Object oriented Concepts above program applying?

1) Class Main inplicitly extends Object so Inheritence?

2) String is an Abstract Data type.

3) Class System and Main are Abstract Data types? i doubt

4) Encapsulation ? i doubt beacuse no data members only methods

anything i left ? anywhere i am wrong?

ppatidar2001, that's a start.

Why do you doubt yourself so much?

Instead of sending in a whining, open-ended question like the one you posed, why not give the list you posted on 3-Oct-2003 and ask if you've missed something? It would have shown that you know a little bit and that you were willing to take some initiative.

I'd say that System.out is a Stream, which is another O-O construct. But that's about it. There's not that much there.

Stop whining and start thinking. You'll get more play on this list if you do. - MOD
