  • Last Updated : 24 Dec, 2018

The hashCode() method of LinkedBlockingDeque in Java is used to get the hashCode value for this instance of the LinkedBlockingDeque. It returns an integer value which is the hashCode value for this instance of the LinkedBlockingDeque.

Syntax:

public int hashCode()

Parameters: This function has no parameters.

Returns: The method returns an integer value which is the hashCode value for this instance of the LinkedBlockingDeque.

Below examples illustrates the LinkedBlockingDeque.hashCode() method:

import java.util.*;
  
public class GFG {
    public static void main(String[] args)
        throws IllegalStateException
    {
  
        // create object of LinkedBlockingDeque
        LinkedBlockingDeque<Integer> LBD
            = new LinkedBlockingDeque<Integer>();
  
        // Add numbers to end of LinkedBlockingDeque
        LBD.add(7855642);
        LBD.add(35658786);
        LBD.add(5278367);
        LBD.add(74381793);
  
        System.out.println("Linked Blocking Deque: " + LBD);
  
        // Get the hashCode value
        // using hashCode() value
        System.out.println("HashCode value: "
                           + LBD.hashCode());
    }
}

Output:

Linked Blocking Deque: [7855642, 35658786, 5278367, 74381793]
