// Java program to get the topmost element from Stack collection 
// without removing it

import java.io.*;
import java.util.*;

public class Main {
  public static void main(String[] args) {
    Stack cars = new Stack();

    cars.push("Maruti");
    cars.push("Tata");
    cars.push("Hundai");
    cars.push("Honda");

    System.out.println("Elements from top of Stack: " + cars.peek());
    System.out.println("Stack elements: \n" + cars);
  }
}

Output:

Elements from top of Stack: Honda
Stack elements: 
[Maruti, Tata, Hundai, Honda]

Explanation:

In the above program, we imported the "java.io.*" and "java.util.*" packages to use the Stack collection class. Here, we created a class Main. The Main class contains a main() method. The main() method is the entry point for the program.

In the main() method, we created a Stack collection and add elements to it. Then we got an element from the TOP of the stack using the peek() method and printed the result.
