Write a method that returns the union of two arrays lists of integers using the following header:
Public static ArrayList union (Array list, ArrayList list2)
For example, the addition of two array lists (2,3,1,5) and (3,4,6) is (2,3,1,5,3,4,6).
Write a test program that prompts the user to enter two lists, each with five integers, and displays their union. The number are separated by exactly one space. Here is a sample run:
Enter five integers for list1: 3 5 45 4 3
Enter five integers for list2: 33 51 5 4 13
The combined list is 3 5 45 4 3 33 51 5 4 13
