Question

Below is come code that I am having trouble understanding. The output is 13 15 x=6. I understand how we get the number 13 because when we go through the loop the value of x is 5 and its corresponding y value is 12. So if x > 4 we then increment y which gives u the value of 13. The next number printed out then should be 14 because the next value of x is 6 and its corresponding y value is 13 so when you increment that it will be 14. However when I run the code its gives a different answer. Can anyone please help? Thanks

public class Output {
  public static void main(String[] args) {
    Output o = new Output();
    o.go();
  }


  void go() {
    int y = 7;
    for (int x = 1; x < 8; x++) {
        y++;
        if (x > 4) {
            System.out.print(++y + " ");
        }
        if (y > 14) {
            System.out.println(" x = " + x);
            break;
        }
    }
  }
}  ​

The reason is because ++y increments y before printing it.

y++ would do what you are expecting
