Java Programming Exercise: Creating and implementing a UML class diagram The inventory of a library is a set of media. Media can be books, CDs and films. Each medium has a unique alphanumeric ID, a title, a year of publication and the date on which it was purchased. Each book also has an author and an ISBN. For each CD the artist and the number of titles are saved. Each movie has a genre and a format: either DVD or...

Java -Create an interface and implement it In the murach.db package, create an interface named IProductDB. This interface should specify this abstract method: public abstract Product get(String productCode); Modify the ProductDB class so it implements the IProductDB interface. Write the code for the new ‘get’ method. Then remove the getProductByCode method. In the Main class, modify the code so it works with the new ProductDB class. This code should create an instance of the IProductDB interface like this: IProductDB db...

In this lab you will work with abstract classes/interfaces. (Java Program) You will be implementing a basic employee schema within a company. The Employee class will be an abstract class that will contain methods applicable to all employees. You will then create 2 classes called SoftwareEngineer and ProductManager. Both are different employee types based on occupation. You will create an interface called Developer which will consist of specific methods that apply to only Developers (e.g. SoftwareEngineer class will implement this,...

For this week's lab, you will use two of the classes in the Java Collection Framework: HashSet and TreeSet. You will use these classes to implement a spell checker. Set Methods For this lab, you will need to use some of the methods that are defined in the Set interface. Recall that if set is a Set, then the following methods are defined: set.size() -- Returns the number of items in the set. set.add(item) -- Adds the item to the...

Please help with this Java Program. Thank you! we will be implementing an Ordered List ADT. Our goal is to implement the interface that is provided for this ADT. Notice that there are two interfaces: OrderedListADT builds on ListADT. In this homework, you'll only be responsible for the OrderedListADT. Figure 1: UML Overview 1 Requirements Create a doubly linked implementation of the OrderedListADT interface. Note that the book includes most of the source code for a singly linked implementation of...

QUESTION The ReadFile class opens and reads a text file. The WriteFile class opens and writes to a file. Compile and run these programs. There are several ways to read/write text files. The examples shown here are just one way of achieving this. Look at the API for the BufferedReader class. The readline() method is a simple way to read the text file line by line. It returns null when the end of the file has been reached. https://docs.oracle.com/javase/8/docs/api/java/io/BufferedReader.html Look...

In this assignment you will be implementing a weather forecaster. It involves writing 3 different classes plus a driver program. It is recommended that you write one class at a time and then write a driver (tester) program to ensure that it works before putting everything together. Alternately, you can use the Interactions tab of JGRASP to test some of the early classes. This is discussed in the next few pages. The Season Class The first, shortest, and easiest class...
