Compare Two Java double arrays

To compare two Java double arrays, use the Arrays.equals() method. The following are our double arrays.

double[] arr1 = new double[] { 1.3, 7.2, 4.2 }; double[] arr2 = new double[] { 1.3, 7.2, 4.2 }; double[] arr3 = new double[] { 2.8, 5.3, 9.8 }; double[] arr4 = new double[] { 2.9, 5.8, 7.8 };

Now, let us compare the above arrays. Two of these arrays will be compared at once.

Arrays.equals(arr1, arr2); Arrays.equals(arr1, arr3); Arrays.equals(arr1, arr4);

The following is the final example to compare Java double arrays.

Example

 Live Demo

import java.util.*; public class Demo {     public static void main(String args[]) {        double[] arr1 = new double[] { 1.3, 7.2, 4.2 };        double[] arr2 = new double[] { 1.3, 7.2, 4.2 };        double[] arr3 = new double[] { 2.8, 5.3, 9.8 };        double[] arr4 = new double[] { 2.9, 5.8, 7.8 };        System.out.println(Arrays.equals(arr1, arr2));        System.out.println(Arrays.equals(arr1, arr3));        System.out.println(Arrays.equals(arr1, arr4));        System.out.println(Arrays.equals(arr2, arr3));        System.out.println(Arrays.equals(arr2, arr4));     } }

Output

true false false false false
