Arrays: Identical arrays

package Ch7;

/*
    Q: 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.
