- Create a class Animal with a constructor that takes no parameters and has an instance variable: private int energy; When an animal is "born," it has one unit of energy. It has the methods: public void eat(int amountToEat) - which increases the amount of energy the animal has by amountToEat public void move(int amountToMove) - which decreases the energy the animal has by amountToMove. public int getEnergy() - which returns the amount of energy left Notice there is no setEnergy method. Energy is only changed by eating or moving. You should also create a subclass BetterAnimal which has a cap on the amount of energy an animal can have. The constructor takes a parameter that specifies a maximum for energy. You will need to save this in another instance variable. Override the eat and move methods In the eat method: If the amount the BetterAnimal eats would set its energy above the max, the energy level is only increased to the max. Also energy is only changed if the amount > 0 In…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); }You need 5 java classes and these include Netflix Class (Parent class of Movie and TVShow class) Movie Class TVShow Class Test/TestDriver Class Database Class Please read the questions carefully. TestDriver is given for the other image.
- Classes – Write a class to represent a AlternativeEnergyCar. Select the fields and methods that fit the modeling of an alternative energy car. Make sure to include code for the constructors, set/get methods, a toString() method.Java Problem. compile and run the code below: /** A class to test the Door class.*/public class DoorTester{ /** Tests the methods of the Door class @param args not used */ public static void main(String[] args) { Door frontDoor = new Door("Front", "open"); System.out.println("The front door is " + frontDoor.getState()); System.out.println("Expected: open"); }} Create a second Door object called “backDoor” with the name property “Back” and an initial state of “closed”. Verify that the object was properly created. Use the mutator to change the state of object backDoor to “open”. Verify that the mutator is working. Create a third Door object called “sideDoor” with the name property “Side” and an initial state of “open”. Verify that the object was properly created. Use the mutator to change the name of object sideDoor to “Front”. Verify that the mutator is working.Define the Circle2D class that contains: Two double data fields named x and y that specify the center of the circle with get methods. A data field radius with a get method. A no-arg constructor that creates a default circle with (0, 0) for (x, y) and 1 for radius. A constructor that creates a circle with the specified x, y, and radius. A method getArea() that returns the area of the circle. A method getPerimeter() that returns the perimeter of the circle. A method contains(double x, double y) that returns true if the specified point (x, y) is inside this circle. See Figure 10.14(a). A method contains(Circle2D circle) that returns true if the specified circle is inside this circle. See Figure 10.14(b). A method overlaps(Circle2D circle) that returns true if the specified circle overlaps with this circle. See the figure below. Figure (a) A point is inside the circle. (b) A circle is inside another circle. (c) A circle overlaps another circle. Draw the UML diagram for the class.…
- An object of the class Timer is used to indicate when a certain amount of time (in seconds) has elapsed, after which it provides a “DING”. The required data field is remainingTime which is the number of seconds until the “DING”. When a Timer object is constructed, it is set with the desired number of seconds. When the timer “ticks”, it is one second closer to the “DING”. This is represented with the tick() method. The dingCheck() method indicates whether the timer should be “DINGING”. Provide the code for the constructor method, and the methods getRemainingTime(), tick(), and dingCheck(). public class Timer { // Methods // Data private int remainingTime; }Define the Circle2D class that contains: Two double data fields named x and y that specify the center of the circle with get A data field radius with a get A no-arg constructor that creates a default circle with (0, 0) for (x, y) and 1 for radius. A constructor that creates a circle with the specified x, y, and radius. A method getArea() that returns the area of the circle. A method getPerimeter() that returns the perimeter of the circle.

- Using Java code the following problem: Write a class called Counter that represents a simple tally counter, which might be used to count people as they enter a room. The Counter class should contain a single integer as instance data, representing the count. Write a constructor to initialize the count to zero. Write a method called click that increments the count and another method called getCount that returns the current count. Include a method called reset that resets the counter to zero. Finally, create a driver class called CounterTest that creates two Counter objects and tests their methods.Write an interactive version of the InchesToFeet class that accepts the inches value from a user.Create a World class and then create a hello world method. The hello world method needs to return the message filed that contains the message "Hello World".
