ArrayList to LinkedList

Problem statement – Add all the elements of ArrayList to the linked list

Logic

• Create an ArrayList and add elements to it.
• Create a Linked list to store all the elements of the ArrayList
• Now add all the elements of a linked list to the array list
• Print all the elements of the LinkedList
• That’s it

Code

package LinkedList;

import java.util.ArrayList;
import java.util.LinkedList;
import java.util.List;

public class ArrayListToLinkedList {
    public static void main(String[] args) {
        // Create an ArrayList
        List<Integer> arrayList = new ArrayList<>();
        arrayList.add(1);
        arrayList.add(2);
        arrayList.add(3);

        // Create a LinkedList
        LinkedList<Integer> linkedList = new LinkedList<>();

        // Add elements from ArrayList to LinkedList
        linkedList.addAll(arrayList);

        // Print the LinkedList
        for (int i : linkedList) {
            System.out.println(i);
        }
    }
}
