Question

How do I make this work? It says that I need to add a return statement but I have one.

public boolean clockFactCheck(int a, int b){
    for (int i = 0; i <= 276; i++){
        for (int h = 0; h <= 55; h++){
            if (a == i + 186 && b == h + 133){
                return true;
            } else {
                return false;
            }
        }
    }
}

Answer 1

The code provided may not reach one of the returns for any input a,b and that’s what the compiler is complaining about.

Actually in your case the if-else will be reached with the very first iteration – unfortunately something which the compiler cannot deduce. Therefore, it goes the save way and issues this error.

Comment: Therefore, in your loop seems not to make much sense since it will not iterate at all but stop within the first iteration i==0 and h==0. Did you meant to code something like that?
