Reg. post increment operator

[Shruti Bakshi]

Hi,
Can someone throw light on how the output of following code snippet is 0 ?

int i =0;
i = i++;
System.out.println(i);

What happens to ++ ? Why is i not incremented after the assignment ?

[Guddu Jhakas]

here value of i is assigned first than it is post incrimented.
samjhe baaboo??

Shruti,
as u know about the post increment operators,
when post increment operator is applied to a variable j:
first the current value of j is the value of the expression, and then later on the value of j increments.
suppose u have

 
int j = 1;
int result = j++;

So the final value is evaluated as:
1)result = j;
2)j = j + 1;
3) return result;

Now solving ur question this way, u get
result = i;
i = i + 1;
i = result;

Thats how it gets solved
Hope u r clear
also look at this
