- In Java, Create a class Rectangle with double attributes length and width. The default constructor should set these attributes to 1. Provide methods that calculate the rectangle's perimeter and area, as well as accessors and mutators for both data fields. The mutator methods for length and width should verify that the number being passed in is larger than 0.0 and less than 20.0 -- if it doesn't fit those criteria, the value of the field should not be changed.Write a Driver class in the same file to test your Rectangle class. It should prompt the user to enter a length and width of a rectangle, and then print out the area and perimeter of the rectangle. (Use the mutators to set the length and width of the rectangle, not the constructor.)Write a Java program for a class called MyPoint, which models a 2D point with x and y coordinates, is designed as shown in the class diagram. It contains: Two instance variables x (int) and y (int). A default (or "no-argument" or "no-arg") constructor that construct a point at the default location of (0, 0). A overloaded constructor that constructs a point with the given x and y coordinates. Getter and setter for the instance variables x and y. A method setXY() to set both x and y. A method getXY() which returns the x and y in a 2-element int array. A toString() method that returns a string description of the instance in the format "(x, y)". A method called distance(int x, int y) that returns the distance from this point to another point at the given (x, y) coordinates, e.g.,MyPoint p1 = new MyPoint(3, 4); System.out.println(p1.distance(5, 6)); An overloaded distance(MyPoint another) that returns the distance from this point to the given MyPoint instance (called another), e.g.,MyPoint…I need help with: The following is a class definition for a simple Ebook. Two instance variables and one parameterless constructor are provided. Part 1: Write a second Java constructor that takes a String array of pages as input and sets the String array instance variable equal to the input. Continue to default the page number to zero. Part 2: Write a getter and a setter Java method for the current page number variable. The setter should check to make sure that the input is a valid page number and only update the variable if the new value is valid. Part 3: Write a getCurrentPage method that returns the String of the current page indexed by current_page. public class Ebook { private String[] pages; private int current_page; //constructor public Ebook() { this.pages = {"See Spot.", "See Spot run.", "Run, Spot, run."}; this.current_page = 0; } }
- I need to write a jave program to keep track of a team sport.

Now, create an object for each of the class and call 1 - method of parent class by object of parent class 2 - method of child class by object of child class 3 - method of parent class by object of child class In the above example, declare the method of the parent class as private and then repeat the first two operations (You will get error in the third).Write a java program that has:A class RentedVehicle that has:- One private instance variable baseFee of type double- One constructor to initialize the instance variable- One instance method getCost () that returns the base fee- Accessor methods for the instance variablesA subclass FuelVehicle that :- has one additional private instance variable Kms indicating the total number of kilometers traveled.- one constructor to initialize the instance variables.- one instance method getMileageFees to return the fees due to mileage based on the following:If Kms < 100 mileagefees=0.2*kmsIf 100<=Kms<= 400 mileagefees=0.3*kmsIf Kms>400 mileagefees=0.3 times 400 plus 0.5 times the extra kilometers above 400.- accessor methodsA Car class which is a subclass of FuelVehicle that :- has one additional private instance variable nbSeats- has one constructor to initialize the instance variables- overrides getCost method by adding nbseats*baseFee to mileageFees- accessorsA Truck class which is a…

Define getter and setter for all the fields. In the setter method, if age is less than 0, print that Age is less than zero. Similarly, if marks is less than zero or greater than 100, print in correct marks and don’t assign marks to member variable. In the Test class, create student’s object and assign the marks and age to appropriate values. Try assigning incorrect values to check if getter and setter methods work as expected.//I have a line of Java code that is giving me an error I do not understand.
