Compare Two Java int Arrays in Java

To compare two Java short arrays, use the Arrays.equals() method.

Let us first declare and initialize some int arrays.

int[] arr1 = new int[] { 33, 66, 12, 56, 99 };
int[] arr2 = new int[] { 33, 66, 12, 56, 99 };
int[] arr3 = new int[] { 33, 66, 15, 56, 90 };

Now let us compare any two of the above arrays.

Arrays.equals(arr1, arr2));

In the same way, work it for other arrays and compare them

Example

 Live Demo

import java.util.*;
public class Demo {
   public static void main(String[] args) {
      int[] arr1 = new int[] { 33, 66, 12, 56, 99 };
      int[] arr2 = new int[] { 33, 66, 12, 56, 99 };
      int[] arr3 = new int[] { 33, 66, 15, 56, 90 };
      System.out.println(Arrays.equals(arr1, arr2));
      System.out.println(Arrays.equals(arr2, arr3));
      System.out.println(Arrays.equals(arr3, arr1));
   }
}

Output

true
false
false
