Design a class named Person with fields for holding a person's name, address, and telephone number (all as Strings). Write a constructor that initializes all of these values, and mutator and accessor methods for every field. Next, design a class named Customer, which inherits from the Person class. The Customer class should have a String field for the customer number and a boolean field indicating whether the customer wishes to be on a mailing list. Write a constructor that initializes these values and the appropriate mutator and accessor methods for the class's fields. Demonstrate the Customer class in a program that prompts the user to enter values for the customer's name, address, phone number, and customer number, and then asks the user whether or not the customer wants to receive mail. Use this information to create a customer object and then print its information. Put all of your classes in the same file. To do this, do not declare them public. Instead, simply write: class Person…
Define a class named Employee. This class should extend the Person class from the previous question. The class should have a constructor, which takes the name, age, employer (String) and salary (int) as parameters (in that order). The first two parameters should be passed to the constructor of the superclass and the value of the last two parameters should be stored in instance variables. The class should define the methods, getSalary which returns the salary of the employee and getEmployer which returns the name of the employer. Any methods from the previous question that need to be overridden should be overridden! Use super and instanceof as appropriate. I.e., for the following methods you should be able to call the method in the superclass for specific situations (e.g. the compareTo method in the superclass can be called if you receive anything other than an Employee, and this also holds for the equals method). The toString method only needs to append details and as such can also…
Design a class named Person with properties for holding a person’s name, address, and telephone number. Next, design a class named Customer, which is derived from the Person class. The Customer class should have a property for a customer number and a Boolean property indicating whether the customer wishes to be on a mailing list. Demonstrate an object of the Customer class in a simple application.
Design a Friend class that the following members: • A field for the name of the friend (a string). •A field for the cell phone number of the friend (a string). • A field for the gender of the friend (a character F or M). • A static field numObjects (integer). Constructors: A default constructor and a parameterized constructor. Accessors methods for the data fields. Set methods for the cell phone data field and the numObjects field. A toString() method that displays the data fields. Design a testFriend driver class that has an arrFriends array that can hold up to a maximum of 15 objects. Write a static fillArray() method that receives the arrFriends array and allow the user to enter the information of a number of friends. Save the objects to the array. Return the array to the call statement. Write a static displayArray) method that receives the arrFriends array as parameter and display a numbered list of information on the objects saved in the array. Write a static sortData() method…
Write the code below for the Computer class. The Computer class must be an abstract class, and have the following methods and attributes: • a public string called HostName • a private int called MemorySize • a public abstract method called shutdown that takes no arguments and returns nothing • a public abstract method called runProgram that takes a String for the name of the program and returns a boolean. • Also include getter/setter methods for the attributes
Java Object Oriented Programming Create a Shape class that shall have color and filled instance variables of enum Color and boolean type. The filled boolean variable shall show, whether the shape is filled (colored). The enum Color shall be defined within the class having 4 color names (choose any four). Also define getArea and getPerimeter method in Shape class, both shall return 0. Create Rectangle class with length and width attributes and a Circle class with radius attribute, of type double. Properly encapsulate all fields. Circle and Rectangle shall extend Shape class and override getArea and getPerimters methods as per its type and specific formula. In Test class, create an object of Rectangle and Circle, by initializing all attributes in constructor and print both shapes' area and perimters. In Test class, define a static method with following signature, public static void printEachShapeCount(Shape... shapes) As you know, the parent type variable can hold the…
Design a LandTract class that has two fields (i.e. instance variables): one for the tract’s length(a double), and one for the width (a double). The class should have:  a constructor that accepts arguments for the two fields  a method that returns the tract’s area(i.e. length * width)  an equals method that accepts a LandTract object as an argument. If the argument object holds the same data (i.e. length and width) as the calling object, this method should return true. Otherwise, it should return false.  a toString method (that returns a String representation of the tract’s length, width, and area). Demonstrate the class in a program by creating an array of three LandTract objects initialized with user input. Then, print the info of the LandTract objects stored in the array by invoking the toString method (implicitly or explicity). Also, use the equals method to compare at least two LandTract objects and print wether they are of equal size or not. Sample Output:…
Java Programming problem Create a checking account class with three attributes: account number, owner’s name, and balance. Create constructor, getters and setters. If one is to set the initial balance of an account as a negative value in a setter or a constructor, remind the user about the error and set it as 0. Create a CheckingAccountDemo class, and create a main method in which Ask for the name, account number, and initial balance for one account from the keyboard input. With these input values as arguments in a call to the constructor, create a CheckingAccount object. Print the summary of this account that includes information on the name, account number, and balance by calling the getters.
Exercise 2 Design a class named Customer with field holding for customer's name, address, and telephone number. Customer's name and address can only be accessed by Customer class. Telephone number can only be accessed by its subclass. Write two overloading constructors and the appropriate setter and getter methods for the class's fields. A retail store has a preferred customer plan where customers can earn discounts on all their purchases. The amount of a customer's discount is determined by the amount of the customer's cumulative purchases in the store as follows: • When a preferred customer spends RM500, he or she gets 5 percent discount on all future purchases • When a preferred customer spends RM1,000, he or she gets 6 percent discount on all future purchases • When a preferred customer spends RM1,500, he or she gets 7 percent discount on all future purchases When a preferred customer spends RM2,000 or more, he or she gets 10 percent discount on all future purchases Design a class…
