Advertisements


Description

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

Declaration

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

public static int hashCode(long[] a)

Parameters

  • a -- This is the array whose hash value to compute.

Return Value

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

Exception

  • NA

Example

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

package com.tutorialspoint;

import java.util.Arrays;

public class ArrayDemo {

   public static void main(String[] args) {
    
   // initializing long array
   long[] lval = new long[] { 87, 77 };

   // hashcode for value1
   int retval = lval.hashCode();
   
   // printing hash code value
   System.out.println("The hash code of value1 is: " + retval);
   
   // value2 for double array
   lval=new long[] { 139, 85 };
    
   // hashcode for value2
   retval=lval.hashCode();

   // printing hash code value
   System.out.println("The hash code of value2 is: " + retval);
   }
}

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

The hash code of value1 is: 4072869
The hash code of value2 is: 1671711
