How do I compare if two arrays are equal?

Using Arrays.equals() methods we can compare if two arrays are equal. Two arrays are considered to be equal if their length, each element in both arrays are equal and in the same order to one another.

package org.kodejava.util;

import java.util.Arrays;

public class CompareArrayExample {
    public static void main(String[] args) {
        String[] abc = {"Kode", "Java", "Dot", "Org"};
        String[] xyz = {"Kode", "Java", "Dot", "Org"};
        String[] java = {"Java", "Dot", "Com"};

        System.out.println(Arrays.equals(abc, xyz));
        System.out.println(Arrays.equals(abc, java));
    }
}

The Arrays.equals() can be used to compare array of any primitive data type and array of Object. If you run this example you will have a result as follows:

true
false
