LinkedList to ArrayList
Problem statement – Add all elements of LinkedList into ArrayList
Logic
- Create a LinkedIn list and add elements to it.
- Create a list to store all the elements of the linked list
- Now add all the elements of a linked list to the array list
- Print all the elements of the array list
- That’s it
Code
package LinkedList; import java.util.ArrayList; import java.util.LinkedList; import java.util.List; public class LinkedListToArrayList { public static void main(String[] args) { //create linkedlist and add elements to it LinkedList<Integer>linkedList=new LinkedList<>(); linkedList.add(1); linkedList.add(2); linkedList.add(3); //Create a list to store all the elements of linked list List<Integer>list=new ArrayList<>(); // Corrected loop to iterate over linkedList, not list for(Integer i:linkedList){ list.add(i); } //printing elements of list one by one for(int i:list){ System.out.println(i); } } }
