How do I convert an array to a list in Java?
I used the Arrays.asList() but the behavior (and signature) somehow changed from Java SE 1.4.2 (docs now in archive) to 8 and most snippets I found on the web use the 1.4.2 behaviour.
For example:
int[] spam = new int[] { 1, 2, 3 };
Arrays.asList(spam)
- on 1.4.2 returns a list containing the elements 1, 2, 3
- on 1.5.0+ returns a list containing the array spam
In many cases it should be easy to detect, but sometimes it can slip unnoticed:
Assert.assertTrue(Arrays.asList(spam).indexOf(4) == -1);
