Create an AlienType class. Include at least three protected data members of your choice, such as the number of eyes the Alien has. Include a constructor that requires a value for each data field and an output method that returns a String containing a complete description of the Alien. Save the file as AlienType.cpp. Create two classes—MartianType and JupiterianType—that descend from Alien. Supply each with a constructor that sets the Alien data fields with values you choose. For example, you can decide that a Martian has four eyes but a Jupiterian has only two. Save the files as MartianType.cpp and JupiterianType.cpp.Create an application that instantiates one Martian and one Jupiterian. Call the output method with each object and display the results. Save the application as CreateAliens.cpp.
a. Write a class named Student has the following data fields and methods: private int Id private double GPA Constructor to create a Student object with specified name, address, Id and GPA. Accessors and mutators methods for Id and GPA data fields (get and set). A method toString () that returns Id, name and address and GPA. b. Write a test program that creates a Student object with Id:123 Name: Ahmed address: Muscat grade: 2.55 & then call toString () method to display Id, name and address and GPA.
Q3: Define a class named Car that has the following specifications:Two attributes:plateNumber: to keep car’s plate number as String value. speed: to keep car’s current speed as integer value.Seven methods:Car( String pn , int s), a constructor method used to initialize the instantiated objects. setPlateNumber( String pn), act as a set method for the attribute plateNumber. setSpeed( int s), act as the set method for the attribute speed.getPlateNumber(), act as the get method for the attribute plateNumber.getSpeed(), act as the get method for the attribute speed.fines (), returns the amount of traffic fine (500 SR) if car’s speed exceeds 120 k/h, otherwise 0. main(...), act as the main method for the program, and it should do the following:1. Instantiate three objects, namely car1, car2, and car3, using the populated constructor.2. Change the speed value of the first car (car1) to 130.3. Change the plate number of the second car (car2) to “Java123”.4. Print the following statement,The…
Create an car class that will be used by a car shop to keep track of inventory. The following attributes should be present in your automobile class: -private string make-private string model-private string color-private int year-private int mileage. The program should have methods such as: -default constructor-parameterized constructor-add a new vehicle method-list vehicle information (return string array)-remove a vehicle method-update vehicle attributes method. All methods should include try..catch constructs. Except as noted all methods should return a success or failure message (failure message defined in "catch"). 1. Create an additional class to call your automobile class (e.g., Main or AutomobileInventory). Include a try..catch construct and print it to the console. 2. Call automobile class with parameterized constructor (e.g., "make, model, color, year, mileage").a) Then call the method to list the values. Loop through the array and print to the screen. 3. Call the remove…
Create a class Employee a) private and static field nextAvailableID (int): create a static constructor to initialize this field to a random number (hint: you can use Random class). You can assume that IDs are numbers between 1-9999. Since nextAvailableID is static, all the Employee objects will share this field. b) with properties FirstName (string) LastName (string), ID (int): make it read only to allow initializing only with a constructor and then no more. c) Add a constructor to allow setting properties FirstName and LastName. Hint: ID will be initialized to nextAvailableID (make sure to increment nextAvailableID by one) Add ToString Method to display the full name and ID of the employee Then, write a Main method to test your class Employee. Create four Employee objects with references e1, e2, and e3 by providing first and last name of each employee Display the full name and id of each employee - note that each employee will have an automatically generated ID…
FootballTeam ClassDefine a class in the FootballTeam java file that will represent a football team as follows: ● The class has the following three fields which cannot be accessed outside of the class. • name of the team (teamName)• number of wins (numOfWins)• number of losses (numOfLosses)● Write a constructor that accepts the name of the team (n), the number of wins (w), and the number of losses (l) as arguments and sets the class properties to those values. ● Write methods that return the name of the team (getTeamName), the number of wins (getNumOfWins), and the number of losses (getNumOfLosses). ● Next, write a method to increase the numbers of wins by 1 (increaseWins) and another method to increase the number of losses by one (increaseLosses). ● Write a method that returns true when a team has a “good record,” meaning the team has more wins than losses(getRecord).● Write a driver program in the FootballTeamDemo class. ○ In the main method, construct a FootballTeam named…
Activity: Create a collection of objects using Java generics. use java to write code. Create a Month class that can accept integer or String data type as an argument. The parameter type will be decided at run time. For this exercise, we will use Month class to store integer and string values that contains 12 months. For example, the integer value of 12 corresponds to string value of “December.” Use the following minimal class definition for Month class. public class Month<T> { private T month; public void setMonth(T month); public T getMonth(); }; Create a new class, MonthApp. This new class will have main method, and will instantiate Month objects to store month indices and names. Here is an example using arrays. // defineMonth<Integer>[] monthsByNumber = new Month<>[12];Month<String>[] monthsByName = new Month<>[12];// adding valuesmonthsByNumber[0] = new Month<Integer>();monthsByNumber[0].setMonth(1);monthsByName[0] = new…
