Chapter 10 defined the class circleType to implement the basic properties of a circle. (Add the function print to this class to output the radius, area, and circumference of a circle.) Now every cylinder has a base and height, where the base is a circle. Design a class cylinderType that can capture the properties of a cylinder and perform the usual operations on the cylinder. Derive this class from the class circleType designed in Chapter 10. Some of the operations that can be performed on a cylinder are as follows: calculate and print the volume, calculate and print the surface area, set the height, set the radius of the base, and set the center of the base. Also, write a program to test various operations on a cylinder.

Complete the FoodItem class by adding a constructor to initialize a food item. The constructor should initialize the name (a string) 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: Fat: 0.00 g…
In the board game Scrabble, each tile contains a letter, which is used to spell words in rows and columns, and a score, which is used to determine the value of words. The point of this exercise is to practice the mechanical part of creating a new class definition: Write a definition for a class named Tile that represents Scrabble tiles. The instance variables should be a character named "letter" and an integer named "value". Write a constructor that takes parameters named letter and value, and initializes the instance variables. Create getters for both of the attributes. (No setters, so that a Tile is immutable.) Implement the .toString() and .equals methods for a Tile. Your completed Tile class should work with this Main program (Links to an external site.) so that it produces sample output like shown at the end of the program. You can Fork the program to make your own version in Replit, where you can add your Tile.java, or you can copy the program to your own Java development…
Java Question - Based on code, which answer out of the choices "A, B, C, D, E" is correct. Question has one correct answer. Thank you. Part 2 - 10. Given the following code, which statement is true? class Water() { ... }class Juice() extends Water { ... }class Apple() { ... }class ApplePie() { Apple a1 = new Apple(); }class AppleJuice() { Apple a1 = new Apple(); Water w1 = newWater(); } A. Juice is a superclass and Water is a subclass.B. ApplePie is a superclass of Apple.C. ApplePie is a composite class that contains an instance of Apple class.D. AppleJuice is a superclass that contains an instance of Apple class and an instance of Water.E. Water is a composite class that contains an instance of Juice.5
This question involves the design of a class that will be used to produce practice problems. The following StudyPracticeinterface represents practice problems that can be used to study some subject. public interface StudyPractice. { /**Returns the current practive problem */ String getProblem(); /** Changes to the next practice problem */ void nextProblem(); } The MultPractice class is a StudyPracticethat produces multiplication practice problems. A MultPractice object is constructed with two integer values: first integer and initial second integer. The first integer is a value that remains constant and is used as the first integer in every practice problem. The initial second integer is used as the starting value for the second integer in the practice problems. This second value is incremented for each additional practice problem that is produced by the class. For example, a MultPractice object created with the call new MultPractice (7, 3)would be used to create the practice…
Create an interface Wheel with methods setWheels (int c) and getWheels () and a class Vehicle with abstract methods getColor () and getBrand (). Now, create a concrete class Taxi with additional method setDriver (String name) that inherits both Wheel and Vehicle. (Note: Concrete classes don’t have any abstract method)

The total cost of a group of items at a grocery store is based on the sum of the individual product prices and the tax (which is 5.75%). Products that are considered “necessities” are not taxed, whereas products that are considered “luxuries” are. The Product class is abstract, and it has a method called getTotalPrice. Your task is to create two subclasses of Product: NecessaryProduct and LuxuryProduct and implement the getTotalPrice method in each of these classes appropriately. Then modify the driver program to instantiate four products (two necessary and two luxury) and store them in the product array, print out each item in the array, and display the total cost of the items. You should not make any changes at all to Product.java, and you should only add to ShoppingTripStartingCode.java. Do not change any code that is already present Example(Cheese and bread are necessities and soda and candy are luxuries)Cheese…
JAVA help Extend the Person class developed above and derive the following classes: Student,HourlyEmployee, and FulltimeEmployee. Determine an appropriate class inheritancehierarchy. These classes should have following fields, necessary constructors, andappropriate access and modifier methods.For all employees:• DepartmentFull-time employees:• SalaryHourly employees:• Hourly rate• Number of hours worked each week (4 weeks)Student:• Classes taken and grades for each class (Use an ArrayList)The employee class should contain the necessary methods that will print the total hours(four-week total), average hours per week worked by each employee, and the total wagesduring a four-week period.The student class should contain the necessary methods to print the transcript for eachstudent.Write a Tester class to test your classes.
Ro-Sham-Bo. Believe it or not, the classic game of Rock-PaperScissors has many other names. One of them is Ro-Sham-Bo. For this assignment, “Ro” will represent “Rock”, “Sham” will represent Paper, and “Bo” will represent Scissors. You will create a RoshamboPlayer class. It will have three attributes: PlayerName: String RoLimit: int ShamBoLimit: int It will also have an overloaded constructor that sets those three values. It will have two functions: playRound that takes in a string and returns a boolean value, and getName that takes in nothing and returns the PlayerName string. In your driver class for this assignment, you will create two RoshamboPlayer objects with the following values: p1: RoLimit == 30, ShamBoLimit == 60 p2: RoLimit = 40, ShamBoLimit = 85 You may name them whatever you like. You will prompt the user to choose one of these two to play against. Then you will create a loop that prompt the user to either play a round of Roshambo, or quit the game. If the user chooses…
The class definition for an Item is given in the image UML diagram below Note: getInfo() returns a string containing ALL of the state information neatly organized. Part 1: Create a class based on the specification above. Reminder: – means private and + means public. Part 2: a)Write a function/method called “addItem” that takes: An array of items The number of items in the array An integer representing a barcode A string representing the name of an item A string representing the description of an item A double value representing the price The function must create and add the item to the array if there is space. The function must return “true” if the addition was successful and “false” otherwise. b)Write a function/method called “listItems” that takes: An array of items The number of items in the array The function must return a string containing the information on each item in the array. c)Write a function called “pricelookup” that takes : An array of items The number of…
