Submitted by Nidhi, on April 25, 2022

Problem Solution:

In this program, we will create a Stack Collections with a few elements. Then we will get the size of the Stack collection using the size() method.

Program/Source Code:

The source code to get the size of the Stack collection is given below. The given program is compiled and executed successfully.

// Java program to count the items of 
// Stack collection

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

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

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

    System.out.println("Size of Stack: " + stack.size());
  }
}

Output:

Size of Stack: 4

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. Then we get the size of the stack collection using the size() method and printed the result.
