Stack elements() method in Java with Example
  • Difficulty Level : Basic
  • Last Updated : 24 Dec, 2018

The Java.util.Stack.elements() method of Stack class in Java is used to get the enumeration of the values present in the Stack.

Syntax:

Enumeration enu = Stack.elements()

Parameters: The method does not take any parameters.

Return value: The method returns an enumeration of the values of the Stack.

Below programs are used to illustrate the working of the java.util.Stack.elements() method:



Program 1:




// Java code to illustrate the elements() method
import java.util.*;
  
public class Stack_Demo {
    public static void main(String[] args)
    {
  
        // Creating an empty Stack
        Stack<String> stack = new Stack<String>();
  
        // Inserting elements into the table
        stack.add("Geeks");
        stack.add("4");
        stack.add("Geeks");
        stack.add("Welcomes");
        stack.add("You");
  
        // Displaying the Stack
        System.out.println("The Stack is: " + stack);
  
        // Creating an empty enumeration to store
        Enumeration enu = stack.elements();
  
        System.out.println("The enumeration of values are:");
  
        // Displaying the Enumeration
        while (enu.hasMoreElements()) {
            System.out.println(enu.nextElement());
        }
    }
}


Output:

The Stack is: [Geeks, 4, Geeks, Welcomes, You]
The enumeration of values are:
Geeks
4
Geeks
Welcomes
You

Program 2 :




import java.util.*;
  
public class Stack_Demo {
    public static void main(String[] args)
    {
  
        // Creating an empty Stack
        Stack<Integer> stack = new Stack<Integer>();
  
        // Inserting elements into the table
        stack.add(10);
        stack.add(15);
        stack.add(20);
        stack.add(25);
        stack.add(30);
  
        // Displaying the Stack
        System.out.println("The Stack is: " + stack);
  
        // Creating an empty enumeration to store
        Enumeration enu = stack.elements();
  
        System.out.println("The enumeration of values are:");
  
        // Displaying the Enumeration
        while (enu.hasMoreElements()) {
            System.out.println(enu.nextElement());
        }
    }
}


Output:

The Stack is: [10, 15, 20, 25, 30]
The enumeration of values are:
10
15
20
25
30
