write a java method [public static ArrayList merge (ArrayList a, ArrayList b)] that merges two array lists, alternating elements from both array lists. if one array list is shorter than the other, then alternate as long as you can and then append the remaining elements from the longer array list. For example, if a is 1 4 9 16 and b is 9 7 4 9 11, then merge returns the array lists 1 9 4 7 9 4 16 9 11 PLEASE USE THE BASE CODE BELOW PROVIDED

import java.util.ArrayList;

public class myARRAYLIST { public static void main(String[] args) { ArrayList a = new ArrayList(); ArrayList b = new ArrayList(); // Initialize array list a to some values for (int i = 0; i < 4; i++) { a.add((i + 1) * (i + 1)); } // Initialize array list b to some values b.add(9); b.add(7); b.add(4); b.add(9); b.add(11); b.add(21); System.out.println("ArrayList b is "+b); System.out.println("ArrayList a is " +a); System.out.println("merged is" +merge (a,b));

} public static ArrayList merge (ArrayListx, ArrayListy) { ArrayList temp = new ArrayList (x.size() + y.size () ); return temp; } }
