Create a class called Vehicle that has the foll owing instance variables: make: a String representing the make of the v ehicle model: a String representing the model of the vehicle year: an int representing the year the vehicle was made The Vehicle class should also have a static v ariable called numVehicles that keeps track o f the number of Vehicle objects that have bee n created. Create a subclass of Vehicle called Car that h as the following additional instance variable: numDoors: an int representing the number of doors on the car The Car class should have a constructor that takes in four parameters: make, model, year, and numDoors. This constructor should use the super keyword to call the constructor of t he Vehicle class and set the make, model, an d year instance variables. It should also set th e numDoors instance variable. In the main method of your program, create s everal instances of the Car class, and print ou t the values of their instance variables. Also, print out the value of the numVehicles static variable to make sure it is incrementing prop erly.

Write a program named SalespersonDemo that instantiates objects using classes named Real EstateSalesperson and GirlScout. Demonstrate that each object can use a SalesSpeech() method appropriately. Also, use a MakeSale() method two or three times with each object, and display the final contents of each objects data fields. First, create an abstract class named Salesperson. Fields include first and last names; the Salesperson constructor requires both these values. Include properties for the fields. Include a method that returns a string that holds the Salespersons full nameâ€”the first and last names separated by a space. Then perform the following Create two child classes of Salesperson: Real EstateSalesperson and Girl Scout. The Real EstateSalesperson class contains fields for total value sold in dollars and total commission earned (both of which are initialized to 0), and a commission rate field required by the class constructor. The Girl Scout class includes a field to hold the number of boxes of cookies sold, which is initialized to 0. Include properties for every field. Create an interface named ISell able that contains two methods: SalesSpeech() and MakeSale(). In each Real EstateSalesperson and Girl Scout class, implement SalesSpeech() to display an appropriate one- or two-sentence sales speech that the objects of the class could use. In the Real Estatesalesperson class, implement the MakeSale() method to accept an integer dollar value for a house, add the value to the Real EstateSalespersons total value sold, and compute the total commission earned. In the Girl Scout class, implement the MakeSale() method to accept an integer representing the number of boxes of cookies sold and add it to the total field.
write a class called OneItemBag ( OneItemBag.java ). This class represents a bag that can hold any single type of object (decided at bag-creation time), and only one item of that type at a time. You may have a zero-parameter constructor if you want one, but you must have the following three features:1. a method that puts an item in the bag (addItem()) which returns whether or not it was successfully added2. a method that removes an item from the bag and returns it (removeItem()), return null if there is no item3. a method to check if an item is in the bag (hasItem()) which returns true or false
Step 3: Add a basic WineCase class and allow a buyer to select a case of wine to buy. Write a basic WineCase class to represent a case of wine. A WineCase object has four fields: refNo (a unique sequence of letters and digits), description (e.g. "chablis", "white burgundy" or similar), noOfBottles (in the case) and price (the price of the case in pounds). The constructor for the class should be passed suitable arguments to initialise these four fields. Add a selectWineCase() method to the Browser class which allows a browser to choose a case of wine provided that browser is a buyer. This method is passed a WineCase object as a parameter. You should declare a new field wineCase in the Browser class in order to store the case of wine selected. Make the selectWinecase() method print a message to the terminal window about the selection. An example is shown below: Buyer with ID 6732 has selected wine case with reference number LO786, a case of 2018 Pinot…

Write a class named Vehicle with vehicleType, manufactureYear(int) and cost(double) as private data fields. [Hint: VehcleType could be "truck", "4WD", "Bus"] . Add a constructor with any two parameters of the superclass. Write a class named Car which inherits the Vehicle class. Add a non-static private string variable called companyName. Add a constructor in the subclass and a toString() method that prints the Car's data fields in the order VehicleType, manufactureYear, companyName [Hint: Add a toString( ) method in the superclass as well]. Create objects of Vehicle and Car class. Can the object of Vehicle class be stored in an object of Car Class? If yes, write the code. If No, Explain why? ***Student Instruction *** You need to write the complete code as mentioned below: i) The main class with necessary codes. ii) The subclass with necessary codes.iii) The Test class with necessary codes.
Create a class named 'Member' having the following members: Data members 1 - Name 2 - Age 3 - Phone number 4 - Address 5 - Salary It also has a method named 'printSalary' which prints the salary of the members. Two classes 'Employee' and 'Manager' inherits the 'Member' class. The 'Employee' and 'Manager' classes have data members 'specialization' and 'department' respectively. Now, assign name, age, phone number, address and salary to an employee and a manager by making an object of both of these classes and print the value you assigned.
Write a graphical application that contains a class named RV whose objects are the recreational vehicle designed and digitized as described in Knowledge Exercises 20 and 21 (you can design your version as well. Simple car shape is will be appreciated. The class’s private data members should be the vehicle’s body color and (x, y) location. a) Give the UML diagram for the class. It should include a three-parameter constructor, a toString method, a method to input the values of all of an object’s data members, and a show method to draw the RV at its current (x, y) location. b) Progressively implement and test the RV class by adding a method and verifying it before adding the next method. A good order to add the methods to the class is the three-parameter constructor, followed by the toString method, the show method, and finally the inputmethod. The client code should create an RV object using the three-parameter constructor to test all of the methods as they are progressively added to the…

Create a class Course, which has one field: String courseName Create the constructor, accessor, and mutator for the class. Then, in the main method of this class, create an instance of the class with the name "CST1201". Write an equivalent while statement to replace the following for statement for (int i=2; i<100; i=i+2) { System.out.println(i); }
Create an abstract class named Element that holds properties of elements,including their symbol, atomic number, and atomic weight. Include aconstructor that requires values for all three properties and a get method for each value. (For example, the symbol for carbon is C, its atomic number is 6, and its atomic weight is 12.01. You can find these values by reading a periodic table in a chemistry reference or by searching the Internet.) Also include an abstract method named describeElement(). Create two extended classes named MetalElement and NonMetalElement. Each contains a describeElement() method that displays the details of the element and a brief explanation of the properties of the element type. For example, metals are good conductors of electricity, while nonmetals are poor conductors
Create a class called Invoice that a hardware store might use to represent an invoice for an item sold at the store. An Invoice should include four information as instance variables: a part number (type String), a part description (type String), a quantity of the item being purchased (type int) and a price per item (double). Your class should have a constructor that initializes the four instance variables. Provide a set and a get method for each instance variable. In addition, provide a method named getInvoiceAmount that calculates the invoice amount (i.e., multiplies the quantity by the price per item), then returns the amount as a double value. If the quantity is not positive, it should be set to 0. If the price per item is not positive, it should be set to 0.0. Write a tester class named InvoiceTest that demonstrates class Invoice’s capabilities by creating two invoices then changing and printing their characteristics.
