How do I determine whether an array contains a particular value in Java?

_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);
