How do I convert array to collection?

To convert array based data into list / collection based we can use java.util.Arrays class. This class provide a static method asList(Object[] a) that converts array into list / collection.

import java.util.Arrays; import java.util.List; import java.util.Iterator; public class ArraysExample { public static void main(String[] args) { String[] array = {"Happy", "New", "Year", "2006"}; List list = Arrays.asList(array); Iterator iterator = list.iterator(); while (iterator.hasNext()) { System.out.println((String) iterator.next()); } } }

The result of our code is:

Happy
New
Year
2006
