Lesson: 23 | Break/Continue

Notes

The break statement can be used to jump out of a loop.

for (Integer i = 0; i < 10; i++) {
  if (i == 4) {
    break;
  }
  System.debug(i);
}

Output: 0 1 2 3

The continue statement breaks one iteration (in the loop), if a specified condition occurs, and continues with the next iteration in the loop.

for (Integer i = 0; i < 6; i++) {
  if (i == 4) {
    continue;
  }
  System.debug(i);
}

Output: 0 1 2 3 5

You can also use break and continue in while loops:

Integer i = 0;
while (i < 10) {
  System.debug(i);
  i++;
  if (i == 4) {
    break;
  }
}

Output: 0 1 2 3

Integer i = 0;
while (i < 6) {
  if (i == 4) {
    i++;
    continue;
  }
  System.debug(i);
  i++;
}

Output: 0 1 2 3 5
