Yasser, did you really look in the tutorials that Stephan pointed you to? Because you can easily find the answers in there. Here are some more specific links into the relevant tutorial pages:

public: Controlling Access to Members of a Class
static: Understanding Instance and Class Members
void: Returning a Value from a Method
main: A Closer Look at the "Hello World!" Application

If there's still something you don't understand, then please ask more questions here - but please be specific. It's hard to understand a generic "I don't understand it" question.

What happens if you leave it out? Can you compile it? Can you run it?

[Campbell Ritchie]

By the way, it is the usual custom to write

public static void main(String[] args)
{
}

It is better style for the [] to follow "String", not "args".
