Question

This may seem silly, but I’m a bit confused about the following code:

public class Loops{

public static void main(String[] args) {

    int i = 0;
    int j = 2;
    int k = 0;
    boolean continue = i<j;
    while (continue && k < 2) {
        i++;
        j--;
        k++;
    }
    System.out.println(j);
}

}

This program prints 0, but I just don’t understand why it doesn’t print 1. The way I see it, after one loop i = j = 1. And thus continue = false. So if anyone can explain to me the logic behind this I would greatly appreciate it!

Answer 1

continue does not reevaluate itself after every loop iteration because he is defined outside of the loop.
instead, check in the loop condition for i < j

    while (i<j && k < 2) {
        i++;
        j--;
        k++;
    }
