Why compile error occurs at a1 object creation(2nd line)

public class Example {
Example a1= new Example();
public static void main(String args[]){
Example a2 =new Example();
}
}

What is the exact and complete text of the compiler error?

Update: This is even MORE important now that I have copied your code and managed to compile it exactly as it is written here.

There are no compiler error in that code.. Rather a StackOverflowError.
Notice that every instance of you class Example has a new instance of the same class..

This becomes something like this: -

a2 (has) a1 (has) a1 (has) a1 (has) a1 (has) a1 (has) a1 ........... and so on...

So, every instance of Example has another instance of Example, and it keeps going, until StackOverflowError in reached..

*NOTE:- All the a1's above are not the same, they are different instance pointing to different objects.. Since they are instance reference..
