How to convert an Array to a Set in Java

I would like to convert an array to a Set in Java. There are some obvious ways of doing this (i.e. with a loop) but I would like something a bit neater, something like:

java.util.Arrays.asList(Object[] a);

Any ideas?

Like this:

Set mySet = new HashSet<>(Arrays.asList(someArray));

In Java 9+, if unmodifiable set is ok:

Set mySet = Set.of(someArray);

In Java 10+, the generic type parameter can be inferred from the arrays component type:

var mySet = Set.of(someArray);

Be careful

Set.of throws IllegalArgumentException - if there are any duplicate
elements in someArray.
See more details: https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/util/Set.html#of(E...)

If you want an unmodifiable set and you might have duplicate elements in the array, do the following:

var mySet = Set.copyOf(Arrays.asList(array));
