How to convert int[] into List in Java?

Question

How do I convert int[] into List in Java?

Of course, I\'m interested in any other answer than doing it in a loop, item by it

Answer 1

If you are using java 8, we can use the stream API to convert it into a list.

List list = Arrays.stream(arr)     // IntStream 
                                .boxed()        // Stream
                                .collect(Collectors.toList());

You can also use the IntStream to convert as well.

List list = IntStream.of(arr) // return Intstream
                                    .boxed()        // Stream
                                    .collect(Collectors.toList());

There are other external library like guava and apache commons also available convert it.

cheers.
