In this program, we will create a stack of integer elements using Stack Collection. Then we will add elements using the push() method.

Java program to create a stack using Stack collection

The source code to create a stack using Stack collection is given below. The given program is compiled and executed successfully.

// Java program to create a stack using 
// Stack collection

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

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

    stck.push(10);
    stck.push(20);
    stck.push(30);
    stck.push(40);

    System.out.println("Stack elements: \n" + stck);
  }
}

Output

Stack elements: 
[10, 20, 30, 40]

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 integer numbers. And, added elements using the push() method and printed them.
