Hello, I am having trouble with this homework question Q1: Implement a class called Vehicle.a) A class named Vehicleb) Two private data members: brand (string), model (string), price (int).c) Accessors and Mutators function for brand, value, and price.Use following main() to test your class. int main(){Vehicle a;a.setBrand("BMW");a.setModel("X5");a.setPrice(60000);cout<<a.getBrand()<<endl; // print BMWcout<<a.getModel()<<endl; // print X5cout<<a.getPrice()<<endl; // print 60000}
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…

(HINT: Look at the member variables).
The play method in the Player class of the craps game plays an entire game without interaction with the user. Revise the Player class so that its user can make individual rolls of the dice and view the results after each roll. The Player class no longer accumulates a list of rolls, but saves the string representation of each roll after it is made. Add new methods rollDice, getNumberOfRolls, isWinner, and isLoser to the Player class. The last three methods allow the user to obtain the number of rolls and to determine whether there is a winner or a loser. The last two methods are associated with new Boolean instance variables (winner and loser respectively). Two other instance variables track the number of rolls and the string representation of the most recent roll (rollsCount and roll). Another instance variable (atStartup) tracks whether or not the first roll has occurred. At instantiation, the roll, rollsCount, atStartup, winner, and loser variables are set to their appropriate…
The class diagram below shows an Order class that "has a" Customer and zero or more Items. Order class should contain private Customer m_cust; private ArrayList<Item> m_items; public Order(Customer cus t) public void additem(Item i) public String toString() Item class should contain private String m_desc private int m_qty private double m_price public Item(String des c, double price, int qty) public String toString() Customer class should contain private String m_first; private String m_last; public Customer(String first, String last) public String toString() Please create the Order, Customer, and Item classes shown above. I have provided you with a read-only Main class that you can use to test your code. When you have completed the Order, Customer, and Item classes, running the Main program should produce the following output: Order for Smith, Tom Order Items: Greeting Card: 1 at 1.5 Baseball Glove: 1 at 54.0 Notebook: 3 at 2.5 public class Main{ public static void…
Create a class called Jug that represents a jug of liquid. The UML for this class is shown below: Jug private String liquidType private int gallons public Jug public Jug(String type, int gal) public void setGallons() public void getGallons() public String getLiquidType() public boolean isEmpty() Your class should have the following private state: liquidType (a string) gallons (an integer) Your class should have the following constructors: A default constructor that creates an empty jug of water. A constructor that accepts the type of liquid the jug contains, and the number of gallons the jug contains, in that order. Your class should have the following behaviors: A method called setGallons that allows you to set the number of gallons in the jug. A method called getGallons that allows you to get the number of gallons in the jug. A method called getLiquidType that allows you to get the type of liquid in the jug. A method called isEmpty that returns true if the…

Write a class that represents a player in a game. The player should have a name, password,experience points, an inventory array of four strings, and a location x,y. Your class shouldhave mutator and accessor methods for all variables. For example: setName(), getName(). Itshould have a suitable display method. Mutators and accessors should be public but allvariables should be private. To implement get inventory, use string * getInv(); Use the scoperesolution operator to implement larger methods such as display(). Use in class methods forshorter methods such as setName(), getName(). (in C++)Example:void setName(string name){this->name = name;}string *getInv();...string* player::getInv(){return inventory;}Note that in the above method setName “this->” is required for disambiguation. If writtenvoid setName(string n){name = n;}“this->” is not required.Write a test program that creates three players and displays them.Example Output:This program generates three player objects and…

1. I Love Shapes by Codechum Admin Shapes are the best thing in the world! We see them everywhere, from triangular pizza pies to her perfectly shaped almond eyes ? For this program, you are tasked to implement the Shape class. This class should be an abstract class and should have the following properties: private String name private String color private boolean isFlat It should have a constructor with the following signature, public Shape(String name, String color, boolean isFlat), getter methods for all the properties, and a setter method for the color. Then implement two more abstract classes that inherit from this Shape class: TwoDShape and ThreeDShape. The TwoDShape will have the following additional details: Additional property: private int numberOfSides Additional methods: getter for the numberOfSides public abstract double getArea() public abstract double getPerimeter() Constructor with the following signature: public TwoDShape(String name, String color,…
