Peter,

The two references disp and show live on the stack and will be removed when the main method is done

I am not able to get this.

As far as i know objects references live on heap and methods and local variable on stack.

Can you please help me to understand this sentence which you have written. Please

In simple what does mark does and sweep does?
Please answer .

class A { public static void main(String []a) { String disp = new String("dinesh"); String show = new String("alok"); disp= show; show=disp; System.out.println(disp); System.out.println(show); } }
