A class called Book is designed (as shown in the class diagram) to model a book written by one author Write the Author class (which includes 3 instance variables: name (String), email (String), gender(char)). It contains • Four private instance variables: name (String), author (of the class Author you have just created, assume that a book has one and only one author), price (double), and qty (int) • Two constructors: o public Book (String name, Author author, double price) { } o public Book (String name, Author author, double price, int qty){ public methods getName(), getAuthor(0, getPrice(), getQtv0 to print all information.

Use java programming language 1.1 Create a Student Object project. Create a Student class and use the provided UML diagram to code the instance fields, constructors and methods. Note: The module mark is the average of the participation mark and the examination mark - calculate this using the calcModuleMark() method. The determineStNumber() method should compile a student number with the first 3 letters of the student's name, a '#' symbol, and a 3-digit randomly generated number (make use of a for-loop to concatenate these 3-digits). The stNumber data field should be set in the constructor by calling the determineStNumber() method. The toString() method must compile a string to display the student number, participation mark, examination mark, and module mark, formatted in table format.

This question involves the design of a class that will be used to produce practice problems. The following StudyPracticeinterface represents practice problems that can be used to study some subject. public interface StudyPractice. { /**Returns the current practive problem */ String getProblem(); /** Changes to the next practice problem */ void nextProblem(); } The MultPractice class is a StudyPracticethat produces multiplication practice problems. A MultPractice object is constructed with two integer values: first integer and initial second integer. The first integer is a value that remains constant and is used as the first integer in every practice problem. The initial second integer is used as the starting value for the second integer in the practice problems. This second value is incremented for each additional practice problem that is produced by the class. For example, a MultPractice object created with the call new MultPractice (7, 3)would be used to create the practice…
class Point with instance variables as: xCoordinate(int) and yCoordinate(int). Write public instance methods (getters & setters) for each instance variable. Now, write a class Circle with private instance variables as radius and Pi (value is 3.14). Write public setter, getter for radius, Area method for calculating Area, Draw method for radius. Formula for calculating area=pi*r^2 Formula for calculating radius=Math.sqrt(xCordinate^2+yCordinate^2) Extend a Circle class from Point class such as Class Circle extends Point Write a Default constructor in Circle class that sets radius, xCoordinate&yCoordinate to some default value e.g. -1; Write a Parameterized constructor in Circle class which takes xCoordinate, yCoordinate and radius as a parameter. E.g. Circle (int xCoordinate, int yCoordinate, double radius) { this.xCoordinate= xCoordinate; this.yCoordinate= yCoordinate;…

Create a Class Student in which we have three instance variables emp_name, emp_id, and Salary. Write getter and setters for each instance variable. Write another Display method that displays the record of Employee. In Main create five Employee’s Objects. Set their values as required and display as well. In the end Display top three employees with respect to Salary (Display those who have more Salary among all).

1. A Simple Student Class (Easy Version) by Codechum Admin Implement the class Student. This class should contain 4 properties: firstName a string which represents the first name of the student lastName a string which represents the last name of the student age an integer which represents the age of the student isMinor a boolean value which will be true if the age is less than 18 and false otherwise. this will automatically be set every time an instance of this class is created and will automatically be updated appropriately every time the age of the student increases. This class should have a constructor with the following parameters: public Student(String firstName, String lastName, int age) Additionally, it should have the following methods: 1. getName Returns the name of the student in the following format: "{lastName}, {firstName}" 2. increaseAge Increases the age by one (1). This returns nothing. 3. toString Returns the details of the student in a…

(1) Complete two files to submit. ContactNode.java - Class definition ContactList.java - Contains main() method (2) Build the ContactNode class per the following specifications: Private fields String contactName String contactPhoneNumber ContactNode nextNodePtr Constructor with parameters for name followed by phone number Public member methods getName() - Accessor getPhoneNumber() - Accessor insertAfter() getNext() - Accessor printContactNode() Ex: If the name is Roxanne Hughes and the phone number is 443-555-2864, printContactNode() outputs: Name: Roxanne Hughes Phone number: 443-555-2864 (3) Define main() to read the name and phone number for three contacts and output each contact. Create three ContactNodes and use the nodes to build a linked list. Ex: If the input is: Roxanne Hughes 443-555-2864 Juan Alberto Jr. 410-555-9385 Rachel Phillips 310-555-6610 the output is: Person 1: Roxanne Hughes, 443-555-2864 Person 2: Juan Alberto Jr., 410-555-9385 Person 3: Rachel…

A class called Place. A Place will have two attributes: city state A Place will have these methods: default constructor overloaded constructor copy constructor setters and getters for all attributes get State initials – get the abbreviation for the state. You may use a utility or a case structure. (FYI, you don’t have to put all 50 states in, at least have what you have in the file. Pick a few and test. copy() equals() toString() 2. A FunPlace class. A FunPlace will have these attributes: name type (Example house, amusement park, corn maze, escape room) price Place - this will be of the Place class (Aggregation – a class is an attribute inside another class) A FunPlace will have these methods: default constructor overloaded constructor that allows name, type, price and a Place object to be passed in overloaded constructor that allows name, price Place copy constructor all getters all setters equals() copy() method toString() - this will include its Place.
