Array class has a asList() method that helps to convert array to List. This method copies an array into List. When we use asList() method, the array and list both shares the same heap space. When update is made to the list, it reflects the changes to array and vice-versa.

import java.util.Arrays;
import java.util.List;

public class ArrayToList {

	public static void main(String[] args) {
		String[] names = { "Neel", "Clay", "Adams", "Joseph", "Jack" };

		// Converting Array to List 
		List aList = Arrays.asList(names);

		System.out.println("Size of list=" + aList.size());
		System.out.println("aList Values=" + aList);

		//changing the aList values
		aList.set(2, "Dinesh");

		// printing aList values
		for (String name : names) {

If you look at the output below you will notice that, after changing the values in list, the changes reflected in the array.
