postfix operator in java
sout(X++ * ++X * X++)
1) first postfix operator: X++
1.a) X++ "replaced" by 10
1.b) X incremented by one: 10+1=11
At this step it should look like: System.out.println(10 * ++X * X++), X = 11;
2) second POSTfix operator: X++
2.a) X++ "replaced" by 11
2.b) X incremented by one: 11+1=12
At this step it should look like: System.out.println(10 * ++X * 11), X = 12;
3) prefix operator: ++X
3.a) X incremented by one: 12+1=13
3.b) ++X "replaced" by 13
At this step it should look like: System.out.println(10 * 13 * 11), X = 13;
4) evaluating 10*13 = 130, 130*11 = 1430.
