Question

Can some one explain me how post increment works in Java ?

 public static void main(String[] args) { int a = 10; /* * 1. "a" is assigned to "b" * 2. Then a gets incremented by 1 */ int b = a++; System.out.println(b); //prints 10 System.out.println(a); //prints 11 int x = 10; /* * 1. "x" is assigned to "x" * 2. Then "x" is not getting incremented by 1 */ x = x++; System.out.println(x); //prints 10 }

So when we have same variable on both sides result is different. Please explain...

x is being incremented, however after being incremented it is being set back to the old value. — Peter Lawrey

This is because even though you increment x , you are assigning x an older value (in this case 10)
