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.
