Program: Basic LinkedList Operations.


Here we can see example for basic operations like creating object for LinkedList, adding objects into LinkedList, searching an object in LinkedList, whether it is listed under this LinkedList instance or not, checking whether the LinkedList is empty or not, and finally size of the LinkedList.

package com.java2novice.linkedlist;

import java.util.LinkedList;

public class MyBasicOperations {

	public static void main(String a[]){
		LinkedList<String> ll = new LinkedList<String>();
		System.out.println("Size of the linked list: "+ll.size());
		System.out.println("Is LinkedList empty? "+ll.isEmpty());
		System.out.println("Does LinkedList contains 'Grape'? "+ll.contains("Grape"));

[Orange, Apple, Grape, Banana]
Size of the linked list: 4
Is LinkedList empty? false
Does LinkedList contains 'Grape'? true

What is adapter class?
An adapter class provides the default implementation of all methods in an event listener interface. Adapter classes are very useful when you want to process only few of the events that are handled by a particular event listener interface. You can define a new class by extending one of the adapter classes and implement only those events relevant to you.
