Author: Roy McElmurry (on 2010/12/28)

Consider the following method.

public static void ifElseMystery(int a, int b) {
    int c = 2;
    if (a + c < b) {
        c = c + 8;
    } else {
        b = b + 10;
    }
    if (a + c < b) {
        c = c + 8;
    } else {
        b = b + 10;
    }
    System.out.println(b + " " + c);
}

For each call below, indicate what output is produced.

ifElseMystery(4, 15);
ifElseMystery(7, 17);
ifElseMystery(12, 5);
ifElseMystery(16, 8);
