What is the output? class A { public static void main(String args[]) { int i=10; i=i++; System.out.println(i); System.out.println(i); } }

first line11

second line11

O/p first line :10

O/P Second line :10

The answer should be10

because here 

int i=10;

i=i++;

here the i value remain same and it is not a loop (value will be changed based on the loop)

if i=++i in this situation the value become  i=11

first: i=10;

second: i=10;

because here using post increment,thats why it uses next usage only.

here i using next level only,we are not insitialisation to another varaible.
