How can I test if an array contains a certain value?
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?solution:
Arrays.asList(yourArray).contains(yourValue)
Warning: this doesn't work for arrays of primitives (see the comments).
Since java-8
You can now use a
Stream to check whether an array of int, double or long contains a value (by respectively using a IntStream, DoubleStream or LongStream)Example
int[] a = {1,2,3,4};
boolean contains = IntStream.of(a).anyMatch(x -> x == 4);
