Finding if an array contains all elements in another array

Question

I am trying to loop through 2 arrays, the outer array is longer then the other. It will loop through the first and if the 2nd array does not contain that int it will return

Answer 1

contain method is reserved for ArrayList Try this:

public boolean linearIn(int[] outer, int[] inner) {
        for (int i = 0; i < outer.length; i++) {
            for (int j = 0; j < inner.length; j++) {
                if (outer[i] == inner[j])
                    return false;
            }
        }
        return true;
}
