Program: How to compare two arrays and confirm they are equal?

Java Arrays class provides few utility methods. One of the utility method Arrays.deepEquals() helps us to compare two arrays. This method compares the array objects each other, and returns true if both arrays are holding same objects. Below example shows how to compare two arrays.

package com.java2novice.arrays;

import java.util.Arrays;

public class MyArrayDeepEquals {

	public static void main(String a[]){
		String[] strArr = {"JAVA", "C++", "PERL", "STRUTS", "PLAY"};
		String[] strArrCopy = {"JAVA", "C++", "PERL", "STRUTS", "PLAY"};
		System.out.println("Are strArr and strArrCopy same? "
					+Arrays.deepEquals(strArr, strArrCopy));
		String[] strArrMod = {"JAVA", "C++", "PERL", "STRUTS"};
		System.out.println("Are strArr and strArrMod same? "
					+Arrays.deepEquals(strArr, strArrMod));
	}
}

Are strArr and strArrCopy same? true
Are strArr and strArrMod same? false
