The Java.util.Stack.lastElement() method in Java is used to retrieve or fetch the last element of the Stack. It returns the element present at the last index of the Stack.

Syntax:

Stack.lastElement()

Parameters: The method does not take any parameter.

Return Value: The method returns the last element present in the Stack.

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

Program 1:




// Java code to illustrate lastElement()
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 last element
        System.out.println("The last element is: "
                           + stack.lastElement());
    }
}

Output:

Stack: [Welcome, To, Geeks, 4, Geeks]
The last element is: Geeks

Program 2:




// Java code to illustrate lastElement()
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(15);
        stack.add(30);
        stack.add(20);
        stack.add(5);
  
        // Displaying the Stack
        System.out.println("Stack: " + stack);
  
        // Displaying the last element
        System.out.println("The last element is: "
                           + stack.lastElement());
    }
}

Output:

Stack: [10, 15, 30, 20, 5]
The last element is: 5
