The following is a class definition for a simple Ebook. Two instance variables and one parameterless constructor are provided.
Part 1: Write a second 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 current page number to zero.
Part 2: Write a getter and a setter method for the 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; }}
In Python 3, write a program with classes to keep track of phones. Here are the requirements: Create a new class called Phone. The Phone class should have a class attribute for the owner's name. Since all phones have a manufacturer and a model number, your class should take the manufacturer and model number from the constructor and assign them to instance attributes. Your Phone constructor should be able to take the parameters. Override the print method for Phone to output a human-friendly version of the information. Your code should prompt the user for an owner name and then start prompting for the manufacturers and models for all phones for that user until the user enters a 'q' or 'Q'. After the entry print out a list of all the phones.
Create a class “Pizza”, and three sub-classes “Cheese Pizza”, “Pepperoni Pizza” and “VeggiePizza”. The class Pizza will have an attributes pizzaSize of type String and another attribute sizePrice of type double. The attribute sizePrice will give the price of the pizza sizes. The sizes can be small, medium and large and their respective price is Rs 600, Rs 800 and Rs 1000. Implement a method getSizePrice(String size) which returns the price of the size mentioned in parameter. Define a method calculatePrice(String size) which returns a double value.
The three subclasses will have their attribute toppingPrice of type double.
Create a test application where user should be able to:
First select the appropriate Pizza type
Then select the pizza size
The system should then calculate total of price (This total should be total of the pizza size and topping)
Display the complete order along with total price at the end

We compute the area of the circular region by subtracting the area of the inner circle from the area of the outer circle. Define a Circle class that has methods to compute the area and circumference. You set the circle's radius with the setRadius method or via a constructor.arrow_forwardImplement a class RoachPopulation that simulates the growth of a roach population. The constructor takes the size of the initial roach population. The breed method simulates a period in which the roaches breed, which doubles their population. The spray(double percent) method simulates spraying with insecticide, which reduces the population by the given percentage. The getRoaches method returns the current number of roaches. A program called RoachSimulation simulates a population that starts out with 10 roaches. Breed, spray to reduce the population by 10 percent, and print the roach count. Repeat three more times.arrow_forward
- Please help me create a cave class for a Hunt the Wumpus game. You can read the rules in it's entirety of the Hunt the Wumpus game online to get a better idea of the specifications. It's an actual game. INFORMATION: The object of this game is to find and kill the Wumpus within a minimum number of moves, before you get exhausted or run out of arrows. There is only one way to win: you must discover which room the Wumpus is hiding in and kill it by shooting an arrow into that room from an adjacent room. The Cave The Wumpus lives in a cave of 30 rooms. The rooms are hexagonal. Each room has up to 3 tunnels, allowing access to 1, 2 or 3 (out of 6) adjacent rooms. The attached diagram shows the layout of rooms in the cave. The map wraps around such that rooms on the edges (white cells) have neighbors from the opposite edge (blue cells). E.g., the neighbors of room 1 are rooms 25, 26, 2, 7, 6, and 30, and you could choose to connect room 1 to any of these rooms. Observe how room 1…arrow_forwardCreate a class with a method. The method has to decide whether a given year is a leap year or not. Note- A year is a leap year if: • It has an extra day i.e. 366 instead of 365. It occurs in every 4 year e.g. 2008, 2012 are leap years. For every 100 years a special rule applies-1900 is not a leap year but 2000 is a leap year. In those cases, we need to check whether it is divisible by 400 or not. > > ClassAssignmentEx2 ©LeapYearDecider javaclassnotes.assignments javaclassnotes.assignments ClassAssignmentEx2() LeapYearDecider() main(String):void A isLeapYear(int):booleanarrow_forwardMake a class Employee with a name and salary.

- Design a class called Stopwatch. The job of this class is to simulate a stopwatch. It should provide two methods: Start and Stop. We call the start method first, and the stop method next. Then we ask the stopwatch about the duration between start and stop. Duration should be a value in TimeSpan. Display the duration on the console. We should also be able to use a stopwatch multiple times. So we may start and stop it and then start and stop it again. Make sure the duration value each time is calculated properly. We should not be able to start a stopwatch twice in a row (because that may overwrite the initial start time). So the class should throw an InvalidOperationException if its started twice. 1arrow_forwardIn java language Write a Rectangle class. A Rectangle has properties of width and length. You construct a Rectangle object by providing the width and length in that order. If no width and length are provided to the constructor, construct a Rectangle with width 0.0 and length 0.0. We want to be able to get and set both the width and the length independently. We also want to be able to ask for the area of the rectangle and the perimeter of the rectangle. What will the object need to remember? width and length - those are the instance variables. Rectangle class has these constructors : public Rectangle() - Constructs a new rectangle with width and length of 0.0. public Rectangle(double width, double length) - Constructs a new rectangle with the given width and length.

- Please use Java to help me with the assignment below. The assignment: A microwave control panel has four buttons: one for increasing the time by 30 seconds, one for switching between power levels 1 and 2, a reset button, and a start button. Implement a class that simulates the microwave, with a method for each button. The method for the start button should print a message “Cooking for ... seconds at level ...”.arrow_forwardCreate a Right Triangle class that has two sides. Name your class rightTraingle. Code getter and setters for the base and the height. (Remember class variables are private.) The class should include a two-argument constructor that allows the program to set the base and height. The constructor should verify that all the dimensions are greater than 0. before assigning the values to the private data members. If a side is not greater than zero, set the value to -1. The class also should include two value-returning methods. One value-returning method should calculate the area of a triangle, and the other should calculate the perimeter of a triangle. If either side is -1, these functions return a -1. The formula for calculating the area of a triangle is 1/2 * b*h, where b is the base and h is the height. The formula for calculating the perimeter of a triangle is b+h+sqrt (b*b+h*h). Be sure to include a default constructor that initializes the variables of the base, height to -1. To test…arrow_forwardIn python how do you: Complete the FoodItem class by adding a constructor to initialize a food item. The constructor should initialize the name to "None" and all other instance attributes to 0.0 by default. If the constructor is called with a food name, grams of fat, grams of carbohydrates, and grams of protein, the constructor should assign each instance attribute with the appropriate parameter value. The given program accepts as input a food item name, fat, carbs, and protein and the number of servings. The program creates a food item using the constructor parameters' default values and a food item using the input values. The program outputs the nutritional information and calories per serving for both food items. Ex: If the input is: M&M's 10.0 34.0 2.0 1.0 where M&M's is the food name, 10.0 is the grams of fat, 34.0 is the grams of carbohydrates, 2.0 is the grams of protein, and 1.0 is the number of servings, the output is: Nutritional information per serving of None:…arrow_forward
