In this program, we will create a Stack Collections, ArrayList with a few elements. Then we will add an ArrayList into another Stack collection using the addAll() method.

Program/Source Code:

The source code to add an ArrayList into the Stack collection is given below. The given program is compiled and executed successfully.

// Java program to add an ArrayList into 
// Stack collection

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("The Stack is: " + stack);

    ArrayList < Integer > arrList = new ArrayList < Integer > ();
    arrList.add(50);
    arrList.add(60);
    arrList.add(70);
    arrList.add(80);

    stack.addAll(arrList);

    System.out.println("The Stack is: " + stack);
  }
}

Output:

The Stack is: [10, 20, 30, 40]
The Stack is: [10, 20, 30, 40, 50, 60, 70, 80]

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 an ArrayList. Then we added ArrayList into the Stack collection using the addAll() method and printed the result.
