List<String> strings = Arrays.asList(new String[]{"one", "two", "three"});

This is a list view of the array, the list is partly unmodifiable, you can't add or delete elements. But the time complexity is O(1).

If you want a modifiable a List:

List<String> strings = 
     new ArrayList<String>(Arrays.asList(new String[]{"one", "two", "three"}));

This will copy all elements from the source array into a new list (complexity: O(n))

This should be the accepted answer! –  vefthym Sep 16 '14 at 10:14

Use the static List list = Arrays.asList(stringArray) or you could just iterate over the array and add the strings to the list.

import java.util.Collections;

List myList = new ArrayList();
String[] myArray = new String[] {"Java", "Util", "List"};

Collections.addAll(myList, myArray);
