Java.util.Arrays.deepHashCode(Object[]) Method

Description

The java.util.Arrays.deepHashCode(Object[]) method returns a hash code based on the "deep contents" of the specified array.For any two arrays a and b such that Arrays.deepEquals(a, b), it is also the case that Arrays.deepHashCode(a) == Arrays.deepHashCode(b).

Declaration

Following is the declaration for java.util.Arrays.deepHashCode() method

public static int deepHashCode(Object[] a)

Parameters

• a -- This is the array whose deep-content-based hash code to compute.

Return Value

This method returns a deep-content-based hash code for a.

Exception

• NA

Example

The following example shows the usage of java.util.Arrays.deepHashCode() method.

package com.tutorialspoint;

import java.util.Arrays;

public class ArrayDemo {

  public static void main(String[] args) {
    
   //initializing an object array
   Object[] ob={ "tuts","point" };
    
   // deephashcode for object ob
   int retval=Arrays.deepHashCode(ob);
    
   // printing value
   System.out.println("The Hash Code of ob is:" + retval);
  }
} 

Let us compile and run the above program, this will produce the following result:

The Hash Code of ob is:217575569
