How to Compare the two Arrays Content in JAVA?

A simple way is to run a loop and compare elements one by one. Java provides a direct method Arrays.equals() to compare two arrays. Actually, there is a list of equals() methods in Arrays class for different primitive types (int, char, ..etc) and one for Object type (which is base of all classes in Java).

import java.util.Arrays; class Test {     public static void main (String[] args)     {         int arr1[] = {1, 2, 3};         int arr2[] = {1, 2, 3};         if (Arrays.equals(arr1, arr2))             System.out.println("Same");         else             System.out.println("Not same");     } }

Output: Same
