Continue

continue works slightly differently with for loops than how it does with while loops.

Any time you hit a line with continue you will immediately jump back to the top of the loop, but unlike with a while loop, the statement which updates your variable will still run.

~void main() {
for (int i = 0; i < 5; i++) {
    if (i == 2) {
        // i++ will still run
        continue;
    }
    System.out.println(i);
}

// 0
// 1
// 3
// 4
~}

So the above for loop is not equivalent to this while loop.

~void main() {
int i = 0;
while (i < 5) {
    if (i == 2) {
        continue;
    }
    System.out.println(i);

    i++;
}

// 0
// 1
// ... spins forever ...
~}

It is equivalent to this one.

~void main() {
int i = 0;
while (i < 5) {
    if (i == 2) {
        i++
        continue;
    }
    System.out.println(i);

    i++;
}

// 0
// 1
// 3
// 4
~}
