(Java) While-Loop condition

Question

I'm just starting to learn Java in school and now I'm stuck.

public static void main(String[] args) {
    int count = 0;
    int point = 5;
    while(point != count++){
        System.out.println(count);
    }

Console : 1 2 3 4 5

Why is number "5" still printed ? Isn't this while loop supposed to run only if point != count + 1 ? Then it should stop when 5 = 5, isn't it (and "5" wouldn't be printed) ?

Thank a lot.

Answer 1

point != count++

This means compare point and current value of count for inequality and then increment count. So when count is 4 :

1. it will be compared to point (unequal)
2. count will become 5
3. the while loop will run for one iteration
4. it will be compared to point again (equal)
5. the loop is terminated

the prefix increment operator ++count would increment before using the value in a comparison.

Answer 2

because you are doing the comparison == before increment ++, if you want to fix it, change to ++count
