How to Compare Two Arrays in Java

In this example, let’s see how to compare two arrays and confirm they are equal in Java.

Source Code

package com.beginner.examples;

import java.util.Arrays;

public class CompareArray {

	public static void main(String[] args) {
		//Create two array object.
		String[] strArray1 = {"Hi", "Hello World"};
		String[] strArray2 = {"Hi", "Hello World"};
		
		/*
		 * Use the method Arrays.deepEquals() to compare two arrays.
		 */
		boolean result1 = Arrays.deepEquals(strArray1, strArray2);
		System.out.println("Compare result is : " + result1);
		
		//Create different array.
		String[] strArray3 = {"I am different array"};
		boolean result2 = Arrays.deepEquals(strArray1, strArray3);
		System.out.println("Compare result is : " + result2);
	}

}

Output:

Compare result is : true
Compare result is : false
