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:
Program 1:
// 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] HashCode value: 2101973421
Program 2:
// Java Program Demonstrate hashCode()// method of ConcurrentLinkedDeque// when the list contains characters  import java.util.concurrent.ConcurrentLinkedDeque;import java.util.*;  public class GFG {    public static void main(String[] args)        throws IllegalStateException    {          // create object of ConcurrentLinkedDeque        ConcurrentLinkedDeque<String> CLD            = new ConcurrentLinkedDeque<String>();          // Add numbers to end of ConcurrentLinkedDeque        CLD.add("1");        CLD.add("2");        CLD.add("3");        CLD.add("4");          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: [1, 2, 3, 4] HashCode value: 2101973421
