_x000D_ _x000D_ I have a String[] with values like so: public static final String[] VALUES = new String[] {"AB","BC","CD","AE"}; Given String s, is there a good way of testing whether VALUES contains s?

_x000D_ Arrays.asList(yourArray).contains(yourValue) Warning: this doesn't work for arrays of primitives (see the comments). Since java-8 you can now use Streams. String[] values = {"AB","BC","CD","AE"}; boolean contains = Arrays.stream(values).anyMatch("s"::equals); To check whether an array of int, double or long contains a value use IntStream, DoubleStream or LongStream respectively. Example int[] a = {1,2,3,4}; boolean contains = IntStream.of(a).anyMatch(x -> x == 4);
