Java Objects - deepEquals() Method

The java.util.Objects.deepEquals() method is used to compare the given two objects. It returns true if the arguments are deeply equal to each other and false otherwise. Two null values are deeply equal. If both arguments are arrays, the algorithm in Arrays.deepEquals is used to determine equality. Otherwise, equality is determined by using the equals method of the first argument.

Syntax

public static boolean deepEquals(Object a, 
                                 Object b)

Parameters

Return Value

Returns true if the arguments are deeply equal to each other and false otherwise

Exception

NA

Example:

In the example below, the java.util.Objects.deepEquals() method is used to compare the given objects.

import java.util.*;

public class MyClass {
  public static void main(String[] args) {
    //creating Objects
    Object obj1[] = {25, 50, 75, 100};
    Object obj2[] = obj1;
    Object obj3[] = {10, 20, 30};
    
    //comparing obj1 and obj2
    System.out.print("Is obj1 deep equal to obj2: ");
    System.out.println(Objects.deepEquals(obj1, obj2));

    //comparing obj1 and obj3
    System.out.print("Is obj1 deep equal to obj3: "); 
    System.out.println(Objects.deepEquals(obj1, obj3)); 
  }
}

The output of the above code will be:

Is obj1 deep equal to obj2: true
Is obj1 deep equal to obj3: false
