Submitted by Nidhi, on April 22, 2022

Problem Solution:

In this program, we will create a stack represented by Linked List using LinkedList class. Then we will push items into the stack using the push() method and print the created stack.

Program/Source Code:

The source code to insert an item to the stack represented by the LinkedList is given below. The given program is compiled and executed successfully.

// Java program to insert an item to the stack represented 
// by the LinkedList

import java.util.LinkedList;

public class Main {
  public static void main(String[] args) {
    LinkedList < String > stkList = new LinkedList < > ();

    stkList.push("One");
    stkList.push("Two");
    stkList.push("Three");
    stkList.push("Four");

    System.out.println(stkList);
  }
}

Output:

[Four, Three, Two, One]

Explanation:

In the above program, we imported the "java.util.LinkedList" package to use the LinkedList 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 represented by LinkedList using the LinkedList class. Then we inserted the item into the stack using the push() method and printed the result.
