Question

Vulpes · Answer

Here's how you can convert an Array to an ArrayList and then back again to an Array: // ListDemo.java import java.util.*; class ListDemo { public static void main(String[] args) { String[] array = {A B C D}; // convert to list List temp = Arrays.asList(array); ArrayList list = new ArrayList (temp); for(String s: list) System.out.println(s); System.out.println(); // convert back to array String[] array2 = new String[list.size()]; array2 = list.toArray(array2); for(String s: array2) System.out.println(s); } } The output is: A B C D A B C D
