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
?
Answer
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);
