Loops

Loops are similar to if statements, except they repeat execution if the condition is still true.

There are 3 kinds of loops built into Java

- while loop
- for loop
- enhanced for loop

You can abruptly stop a loop by using break.

    for(...) {
		// execute some code

		if(...) {
			break; // exits loop - works with all loops
		}
	}

	// execution continues from here after breaking

Or force the loop to skip to the next iteration by using continue.

    while(...) {
		// execute some code

		if(...) {
			continue; // restsart the loop, but at the next iteration
		}

		// code here isn't executed this iteration if continue is executed
	}

You can also label loops to specify what loop to perform the break or continue on

    first:
	while(...) {
		second:
		for(...) {
			if(...) {
				continue first;
			} else if(...) {
				break second;
			}
		}
	}
