A publishing house prints and distributes two types of publication: books and journals. Each book has a title, an author, an edition number, and an ISBN. Each journal has a title, a volume number, an issue number, and an ISBN. Each of these publication have a statement that prints their properties i. Design the classes needed for the problem specification above using UML class diagram. ii. Convert your UML class diagram in question (1i) into a java program. Create a test class and print out details about the object of the classes. The following object oriented concepts should be used in your program. Data encapsulation, Method Overriding, Method Overloading, Inheritance, Polymorphism, Super to call a constructor and Super to call a method. Please comment your code to show how each of these concepts have been applied. iii. Using your classes in question (1ii), draw a UML sequence diagram to show sequence of interaction between objects at runtime (that is, the flow of controls by method calls)

Refer to the UML class diagram given below: Subject a) |- subjectTitle: String - creditHour: int - subjectCount: int + Subject() + Subject(subjectTitle: String, creditHour: int) + set and get methods + getSubjectCount ():int + toString():String Implement the complete Subject class that shown in the above diagram. The following requirements must be included: • Use this keyword whenever possible. • The getter and setter for all instance data members. • The parameterized constructor should increase the value of subjectCount by 1. • The toString() method that will return all the information about the Subject object except subjectCount.
This programming problem consists of two parts and shall lead you through all the concepts involved in OOP Composition. Part 1: A class called Author (as shown in the class diagram) is designed to model a book's author. It contains: Three private instance variables: name (String), email (String), and gender (char of either 'm' or 'f'); One constructor to initialize the name, email and gender with the given values;public Author (String name, String email, char gender) {......}(There is no default constructor for Author, as there are no defaults for name, email, and gender.) public getters/setters: getName(), getEmail(), setEmail(), and getGender();(There are no setters for name and gender, as these attributes cannot be changed.) A toString() method that returns "Author[name=?,email=?,gender=?]", e.g., "Author[name=Tan Ah Teck,email=ahTeck@somewhere.com,gender=m]". Write the Author class. Also, write a test driver (for testing purpose on your local machine) called TestAuthor to test…
: Imagine you have a call center with three levels of employees: respondent, manager,and director. An incoming telephone call must be first allocated to a respondent who is free. If therespondent can't handle the call, he or she must escalate the call to a manager. If the manager is notfree or not able to handle it, then the call should be escalated to a director. Design the classes anddata structures for this problem. Implement a method dispatchCall () which assigns a call tothe first available employee.
Convert the UML class diagram above into a java code with the following conditions The methods in the Pet class are abstract. Create a class called test. The main() method in the test class should create three Cat objects and two Budgie The main() method should also create indirectly an object of the Pet class. Demonstrate polymorphism in your test
Answer this qustion with refer to the part 1 and part 2 codes only an eample how to write in pic: In this and final part of the course work you are required to change the definition of the Item_in_Stock class to make it an abstract class and change the getItemCat(), getItemName() and getItemDescription() definitions to make them abstract methods. You are then required to design and implement three classes which are derived from Item_in_Stock class to fully demonstrate the concept of inheritance and polymorphism. Implementation of HP_Laptop class in part II should have given you an idea of inheritance and polymorphism. Three sub classes, one class against each category (Computers, Laptops and Accessories), should contain appropriate constructors, instance variables, setter and getters methods and overridden methods for getItemName(), getItemDescription() and get_Item_details() method. You should be creative and come up with your own ideas of sub-classes. Task 3.1. Draw a UML class…
For the following scenario, draw a UML class diagram to illustrate the classes implemented, hierarchical relationship among the classes, data fields and methods. You may use MS Word, MS Paint, or pencil / pen & paper and upload a photo of the diagram. This program is for a bank application. The bank organization includes attributes such as name, routing number, city location. The bank contains several hundred employees, and several thousand customers. Customers may hold checking accounts and / or savings accounts. Transactions include deposits, withdrawals, transfers.
Create an abstract class named capstone with necessary abstract methods in Package 1 and define classes like Inhouse, PAT_Internship and NonPAT_Internship with required data members in sub package 1. Get a choice from student and based on the input from student, create parent reference to hold the respective child object and print the details in Package 2.
Given: UML diagram of an Account object Below. Use Java progaramming Language. Note: The static variables/data fields and methods in UML class diagrams are underlined. Create an Account Object project. 1. Design an Account class and use the provided UML diagram to code the instance fields, constructors and methods. Note: The type of accounts are 1 (Savings) or 2 (Cheque) The constructor must assign the values of the parameters to the data fields/instance variables. The static field must be increased by one in the constructor. The setAccNumber() is a private void method. The account number must consist of the first 3 letters of the name of the account holder, the digit indicating the type of account and #-character and a 3-digit random value. This method must be called from the constructor. The makeDeposit() method must add the amount received as a parameter to the balance if the value received is not a negative value. The withdrawAmount() method must check whether the balance…
Create a UML class diagram using arrows to show the relationships between classes for the following scenario. The class diagram is attached for reference. A parking deck system manages an entry/exit gate, which opens to let a vehicle (i.e., car) into or out of the deck and closes when the car has passed through. A driver must push a button to print a parking permit. When the driver takes the parking permit, the system raises the gate. The system lowers the gate after the vehicle has passed through. A permit id and time of entry is printed on the parking permit, and is also encoded on the permit’s bar code. When the vehicle leaves the parking deck, the driver inserts the parking permit into a bar code reader, which scans the bar code, and then transmits the bar code to the parking system. The parking system calculates a fee that is based on the number of hours that have elapsed since the vehicle entered the parking deck, and displays the fee to the operator and driver. The driver must…
Analysis: Q1: There are common attributes and methods between passengers and drivers. What is the best choice for designing and writing the codes of these two classes? Explain your answer. Q2: Draw a simple class diagram showing only relationships between the classes. Implementation: After analysing the given requirements, implement the required application: with Object Oriented Programming style following the rules of good programming style (e.g. adding comments, etc.) • using only the material covered in M251 (and its prerequisites) Java language*
Problem B Now we are going to use the design pattern for collecting objects. We are going to create two classes, a class AmazonOrder that models Amazon orders and a class Item that models items in Amazon orders. An item has a name and a price, and the name is unique. The Item class has a constructor that takes name and price, in that order. The class also has getters and setters for the instance variables. This is the design pattern for managing properties of objects. The setName() method should do nothing if the parameter is the empty string, and the setPrice() method should do nothing if the parameter is not positive. The class also has a toString() method that returns a string representation for the item in the format “Item[Name:iPad,Price:399.99]”. For simplicity, we assume an Amazon order can have at most 5 items, and class AmazonOrder has two instance variables, an array of Item with a length of 5 and an integer numOfItems to keep track of the number of items in the…
