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.

Live Demo
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
