Question

 public class I {
        public static void main(String  args[])
        {
            int i=0,j=1,k=2;
            i=i++ - --j + ++k;
            System.out.println("\ni : "+i+"\nj : "+j+"\nk : "+k);
        }
    }

Can anyone please explain to me Why the above code gives output :

i : 3
j : 0
k : 3

Instead of giving the output :

i : 4
j : 0
k : 3

?

Answer 1

1. i++ – gives 0 (and increments i)
2. –j decrements and gives 0
3. ++k increments and gives 3
4. the result of 0 + 0 + 3 is assigned to i (which overwrites i’s value 1).

Therefore: i : 3.
