Converting an array of long to ArrayList<Long>

Question

This sadly doesn't work:

long[] longs = new long[]{1L};
ArrayList<Long> longArray = new ArrayList<Long>(longs);

Is there a nicer way except adding them manually?

Answer 1

Using ArrayUtils from apache commons-lang

long[] longs = new long[]{1L};
Long[] longObjects = ArrayUtils.toObject(longs);
List<Long> longList = java.util.Arrays.asList(longObjects);

Answer 2

Since others have suggested external libraries, here's the Google Guava libraries way:

long[] longs = {1L, 2L, 3L};
List<Long> longList = com.google.common.primitives.Longs.asList(longs);

Relevant javadoc for Longs.
