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
