I have a String[] with values like so:

Answer 1

With Java 8 you can create a stream and check if any entries in the stream matches "s":

String[] values = {"AB","BC","CD","AE"};
boolean sInArray = Arrays.stream(values).anyMatch("s"::equals);

Or as a generic method:

public static  boolean arrayContains(T[] array, T value) {
    return Arrays.stream(array).anyMatch(value::equals);
}
