LinkedList Class

LinkedList Class V/S ArrayList Class

In this blog, we will see how to LinkedList Class and ArrayList collection class different with each other.  Both classes can add data using add() method.

But in this blog, we will also see addFirst() and addLast() method do not working in ArrayList class. We also see how to removeFirst() and removeLast() method do not working in ArrayList class.

This is basic different between ArrayList and LinkedList class.

 

Let’s see Example on LinkedList Class V/S ArrayList Class

 

import java.util.*;

class collection5

{

                public static void main(String args[])

                {

                                ArrayList a1 = new ArrayList();

                                a1.add(56);

                                a1.add(78);

                                a1.add(89);

 

                                LinkedList a2 = new LinkedList();

                                a2.add(56);

                                a2.add(78);

                                a2.add(89);

 

                                System.out.println(“ArrayList : ” + a1);

                                System.out.println(“LinkedList : ” + a2);

 

                                //a1.addFirst(90);           

// ArrayList – Error: We can’t use addFirst And addLast method in ArrayList

                                a2.addFirst(90);                // LinkedList

 

                                //a1.removeFirst();        

// ArrayList – Error: We can’t use removeFirst and removeLast method in ArrayList

                                a2.removeFirst();             // LinkedList

                                System.out.println(“ArrayList : ” + a1);

                                System.out.println(“LinkedList : ” + a2);

                }

}

 

Output

ArrayList : [56,78,89]

LinkedList : [56,78,89]

—-  Add | Remove Data From Linked List —

ArrayList : [56,78,89]

LinkedList : [56,78,89]
