ConcurrentLinkedDeque hashCode() method in Java with Example
  • Last Updated : 27 Dec, 2018

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

Syntax:

public int hashCode()

Parameters: This function has no parameters.

Return Value: The method returns an integer value which is the hashCode value for this instance of the ConcurrentLinkedDeque.

Below programs illustrate the ConcurrentLinkedDeque.hashCode() method:

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

Output:

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