public static int looper(int n) {
  int result = 0;
  int a = 0;
  for (int i = 1; i <= n; i++) {
  while (a > 0) {
  return result;

Evaluate looper(2):
Evaluate looper(100):

If you look closely at this program, you'll notice that the for loop and the while loop are quite similar to each other. They're both incrementing a value, and they both depend on a pre-existing, nonzero value to repeat for...

Consider this:

  • Try tracing your variables (n, a, and result) throughout the program.
  • Pay attention to how one variable changes in relation to another.
  • Moreover, try to discern what each loop is doing to its variables. What stands out to you?

looper(2); will end up returning the integer 2.
looper(100); will end up returning the integer 100.
