Chapter 4, Problem 53E

Explanation of Solution

Given: The class named ArrayList is discovered inside the java.util package, which includes another class known as Linked List.

To find:

The information about LinkedList.

The comparison between ArrayList and LinkedList.

The methods that are similar and different between LinkedList and Arraylist.

Solution:

The implementation of LinkedList is slightly different from that of ArrayList in Java. These are:

LinkedList preserves its elements in the form of doubly-linked list whereas in case of ArrayList, it's a simple dynamic array which expands or shrinks according to the number of elements added to it.

We can also insert elements at any place in a LinkedList since it retains the track of linking between previous and next elements, whereas in case of ArrayList we can also insert elements at any position in the list but it requires shifting of all the latter elements to create space for new elements.

When huge number of elements are added to an ArrayList which if crosses its underlying size of the array, then a new array double of its size is reserved and the old array gets copied into the new one. But in case if LinkedList no such thing happens, since its underlying structure is not an array, a list of elements each of which is linked together by its previous and next memory locations.

The methods which are common to both the ArrayList and LinkedList, are given below with their workings:

add(int index, Object element) – used to add an element at particular index of the list.

add(Object element) - appends an element at the termination of the list.

addAll(Collection c) - adds a collection at the termination of the list.

addAll(int index, Collection c) - inserts a collection at a specified index of the list.

clear() - removes all the elements of the list.

clone() - copies an instance of the list to a new array and then returns that array.

contains(Object element) - checks to see that the specified element exists in the list or not. If so, it returns true else returns false.

get(int index) – used to return the element of the stated index of the list.

indexOf(Object element) – used to return an index for the first occurrence of the specific element that is stated in the list if it is found, or else it returns -1...

Given the following request to an AI chatbot, which response is more accurate? (You should use Google to verify that the factual claims in each response are accurate.)   Prompt Is this true? The first recorded use of the phrase "when pigs fly" in print is in a 1616 play by Ben Jonson called "The Devil is an Ass," in which a character says, "When pigs fly, good-night!!" Response   Response A Response B Yes, that's true! The phrase "when pigs fly" indeed appears in Ben Jonson's 1616 play The Devil is an Ass and was said during the second act in a conversation between Fitzdottrel and Pug. The phrase was first used to express skepticism or disbelief, suggesting that something is as unlikely to happen as the fanciful idea of pigs flying. This usage is often cited as one of the earliest instances of the phrase in print.   The claim that the phrase "when pigs fly" was first recorded in Ben Jonson's 1616 play "The Devil is an Ass" is not accurate. There is no evidence from the…

Please answer the homework scenario below and make a JAVA OOP code. You have been hired by GMU to create and manage their course registration portal. Your first task is to develop a program that will create and track different courses in the portal.  Each course has the following properties:  • a course number ex. IT 106, IT 206,  • A course description, ex. Intro to Programming • Total credit hour ex. 3.0, and  • current enrollment ex. 30 Each course must have at least a course number and credit hours. The maximum enrollment for each course is 40 students. The current enrollment should be no greater than the maximum enrollment. A course can have a maximum of 4 credit hour. The DDC should calculate the number of seats remaining for the course. Design an object-oriented solution to create a data definition class for the course object. The course class must define all the constructors, mutators with proper validation, accessors, and special purpose methods. The DDC should calculate the…
