Equivalent Arrays - Comparing 2 User Inputs To Determine If Same

I have been stuck on this for the past 2 hours, basically we have to compare user input, put user input into an array and compare for equivalency. An example of the program:

Array 1: 1 2 3 4 5 6 7 8
Array 2: 1 2 3 4 5 6 7 8
Array 3: 1 2 3 4 5 6 7 8 9
Array 4: 1 2 3 4 5 6 7 8

Array 1 & 2 are equal
Array 1 & 3 are not equal
Array 1 & 4 are not equal.

This cannot be done by importing Java.util.Array at all!! (my research only find this to compare arrays ) which is why I am having trouble starting off. My code thus far:

import java.util.Scanner;
public class Lab07b {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.println("Enter Integer 1:");
int a = input.nextInt();
