Stack hashCode() method in Java with Example

Last Updated : 24 Dec, 2018

The Java.util.Stack.hashCode() method in Java is used to get the hashcode value of this Stack.

Syntax:

Stack.hashCode()

Parameters: The method does not take any parameter.

Return Value: The method returns hash code value of this Stack which is of Integer type.

Below programs illustrate the Java.util.Stack.hashCode() method:

Program 1: Stack with string elements.

// Java code to illustrate hashCode() 
import java.util.*; 
  
public class StackDemo { 
    public static void main(String args[]) 
    { 
        // Creating an empty Stack 
        Stack<String> stack = new Stack<String>(); 
  
        // Use add() method to add elements into the Stack 
        stack.add("Welcome"); 
        stack.add("To"); 
        stack.add("Geeks"); 
        stack.add("4"); 
        stack.add("Geeks"); 
  
        // Displaying the Stack 
        System.out.println("Stack: " + stack); 
  
        // Displaying the hashCode value of Stack 
        System.out.println("The hashCode value is: "
                           + stack.hashCode()); 
    } 
} 

Output:

Stack: [Welcome, To, Geeks, 4, Geeks]
The hashCode value is: -878886256

Program 2: Stack with integer elements.

// Java code to illustrate hashCode() 
import java.util.*; 
  
public class StackDemo { 
    public static void main(String args[]) 
    { 
        // Creating an empty Stack 
        Stack<Integer> stack = new Stack<Integer>(); 
  
        // Use add() method to add elements into the Stack 
        stack.add(10); 
        stack.add(20); 
        stack.add(30); 
        stack.add(40); 
        stack.add(50); 
  
        // Displaying the Stack 
        System.out.println("Stack: " + stack); 
  
        // Displaying the hashCode value of Stack 
        System.out.println("The hashCode value is: "
                           + stack.hashCode()); 
    } 
} 

Output:

Stack: [10, 20, 30, 40, 50]
The hashCode value is: 38490301
