how to add all elements of a list to linkedlist in java?


LinkedList:

The LinkedList class extends AbstractSequentialList and implements the List and Deque interface. It uses linked list data structure to store elements. It can contain duplicate elements. It is not synchronized.

Note: It not provides the random access facility.

We can use addAll() method to add all elements of a list to linkedlist in java.

Example:

package com.codesjava;
 
import java.util.ArrayList;
import java.util.LinkedList;
import java.util.List;
 
public class Test {
  public static void main(String args[]){
	LinkedList<String> linkedList = new LinkedList<String>();
	linkedList.add("Jai");
	linkedList.add("Mahesh");
	linkedList.add("Naren");
	linkedList.add("Vivek");
	linkedList.add("Vishal");
	linkedList.add("Hemant");
	System.out.println("Actual LinkedList:"+linkedList);
	List<String> list = new ArrayList<String>();
        list.add("Ajay");
        list.add("Vikas");
        linkedList.addAll(list);
        System.out.println("After adding: "+linkedList);
  }
}

Output

Actual LinkedList:[Jai, Mahesh, Naren, Vivek, Vishal, Hemant]
After adding: [Jai, Mahesh, Naren, Vivek, Vishal, Hemant, Ajay, Vikas]
