Question: The arrays list1 and list2 are identical if they have the same contents.
Write a method that returns true if list1 and list2 are identical, using the following header:
public static boolean equals(int[] list1, int[] list2)
Write a test program that prompts the user to enter two lists of integers and displays whether the two are identical.
Sample Input/ Output
Enter contents of array 1:
5 2 5 6 6 1
Enter contents of array 2:
5 5 2 6 1 6
The arrays are identical
