Program: Basic LinkedList Operations.


Description:

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.


Code:
package com.java2novice.linkedlist;

import java.util.LinkedList;

public class MyBasicOperations {

	public static void main(String a[]){
		
		LinkedList<String> ll = new LinkedList<String>();
		ll.add("Orange");
		ll.add("Apple");
		ll.add("Grape");
		ll.add("Banana");
		System.out.println(ll);
		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"));
	}
}

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

Interface and its usage
Interface is similar to a class which may contain method's signature only but not bodies and it is a formal set of method and constant declarations that must be defined by the class that implements it. Interfaces are useful for declaring methods that one or more classes are expected to implement, capturing similarities between unrelated classes without forcing a class relationship and determining an object's programming interface without revealing the actual body of the class.
