Submitted by Nidhi, on April 26, 2022

Problem statement

In this program, we will create a Stack Collections with a few elements. Then we will traverse elements of the Stack collection using the foreach loop.

Source Code

The source code to traverse a Stack collection using the "foreach" loop is given below. The given program is compiled and executed successfully.

// Java program to travers a Stack collection 
// using "foreach" loop

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

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

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

    System.out.println("Stack items: ");
    for (int val: stack) {
      System.out.println(val);
    }
  }
}

Output

Stack items: 
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 a Stack collection and add elements. Then we traversed the elements of created Stack collection using the "foreach" loop and printed the result.
