How to determine if an array of strings is contained within another array of strings?

Question

Java

There is a first array of strings: And a second one: all elements of st2 are in st1
String[] st1 = {"I", "am", "Bob"};
String[] st2 = {"I", "Bo"};

Answer 1

private static boolean containsAll(String[] substr, String[] str) {
        for (String s : substr) {
            if (!Arrays.toString(str).contains(s)) {
                return false;
            }
        }
        return true;
    }

Answer 2

You need to go through each element from the second array and find out if it is contained in the first array.
If all are contained, return true, if at least one was not found, return false.
