Functions argument

[GoToLoop]

Given parameters a & b are of datatype int, you can simply return an int[] array:

static final int[] example(final char ch, int a, int b) {
  if (ch == 'y') {
    a *= b;
    b = (a + 5) * (b - 2);
  } else {
    b /= a;
    a += b;
  }

  return new int[] { a, b };
}
