Java program to perform push and pop operations in a Stack collection

Java example to perform push and pop operations in a Stack collection.
Submitted by Nidhi, on April 24, 2022

Problem Solution:

In this program, we will create a stack of hybrid elements using Stack Collection. Then we will perform push, pop operations using push(), pop() methods respectively.

Program/Source Code:

The source code to perform push and pop operations in a stack using Stack collection is given below. The given program is compiled and executed successfully.

// Java program to perform push and pop operations 
// in a Stack collection

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

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

    stck.push(1);
    stck.push("Two");
    stck.push(3.14);
    stck.push(true);

    System.out.println("Stack elements: ");
    System.out.println(stck.pop());
    System.out.println(stck.pop());
    System.out.println(stck.pop());
    System.out.println(stck.pop());
  }
}

Output:

Stack elements: 
true
3.14
Two
1

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 an object of the Stack collection class to store hybrid elements. And, performed push, pop operations of a stack using push(), pop() methods of Stack collection respectively.
