Design a class that holds the following personal data: name, address, age, and phone number. Write appropriate accessor and mutator methods. Also, write a program that creates three instances of the class. One instance should hold your information, and the other two should hold your friends’ or family members’ information.
Create the following class diagram: The print method in: - Author prints the Authors data - Page prints page no and text - Textbook prints the subject and all pages - Novel prints the genre and all pages The toString method in: - Book returns title and authors - textbook returns subject in additions to super toString - Novel genre in additions to super toString Test your implementation create objects of different types example : - Create a book of type Novel which has many pages and several authors - Create a book of type Textbook which has many pages and several authors - Access these objects polymorphically, variable of class book contains objects of its subclasses Textbook and novel - Print a hall book - Print a single page of a book - Print the book and its authors

Java - Constructors Create a class named Book that has the following attributes: Publisher - String Year Published - Integer Price - Double Title - String Create a constructor for the class Book that has the parameters from the attributes of the class. After, create a method for the class that displays all attributes. Ask the user for inputs for the attributes and use the constructor to create the object. Lastly, print the values of the attributes. Inputs 1. Publisher 2. Year Published 3. Price 4. Book Title XYZ Publishing 2020 1000.00 How to Win? Sample Output Published: ABC Publishing Year Published: 2022 Price: 150.00 Book Title: Stooping too low Stooping too low is published by ABC Publishing on 2022. It sells at the price of Php150.00.
Create an Employee Class that will have ● Two instance variable: name and workingPeriod ● A class method named employeeByJoiningYear(): o To create an Employee object by joining year for calculating the working period o It will have two Parameter name and year ● A static method experienceCheck() to check if an Employee is experienced or not o It will take working period and gender as parameter o If an employee’s working period is less than 3, he or she is not experienced [You are not allowed to change the code below] # Write your code here employee1 = Employee('Dororo', 3) employee2 = Employee.employeeByJoiningYear('Harry', 2016) print(employee1.workingPeriod) print(employee2.workingPeriod) print(employee1.name) print(employee2.name) print(Employee.experienceCheck(2, "male")) print(Employee.experienceCheck(3, "female")) Output 3 5 Dororo Harry He is not experienced She is experienced
Design a LandTract class that has two fields (i.e. instance variables): one for the tract’s length(a double), and one for the width (a double). The class should have:  a constructor that accepts arguments for the two fields  a method that returns the tract’s area(i.e. length * width)  an equals method that accepts a LandTract object as an argument. If the argument object holds the same data (i.e. length and width) as the calling object, this method should return true. Otherwise, it should return false.  a toString method (that returns a String representation of the tract’s length, width, and area). Demonstrate the class in a program by creating an array of three LandTract objects initialized with user input. Then, print the info of the LandTract objects stored in the array by invoking the toString method (implicitly or explicity). Also, use the equals method to compare at least two LandTract objects and print wether they are of equal size or not. Sample Output:…

Create an automobile class that will be used by a dealership as a vehicle inventory program. The following attributes should be present in your automobile class: private string make private string model private string color private int year private int mileage Your program should have appropriate methods such as: default constructor parameterized constructor add a new vehicle method list vehicle information (return string array) remove a vehicle method update vehicle attributes method. All methods should include try..catch constructs. Except as noted all methods should return a success or failure message (failure message defined in "catch"). Create an additional class to call your automobile class (e.g., Main or AutomobileInventory). Include a try..catch construct and print it to the console. Call automobile class with parameterized constructor (e.g., "make, model, color, year, mileage"). Then call the method to list the values. Loop through the array and print to the screen.…

2019 AP® COMPUTER SCIENCE A FREE-RESPONSE QUESTIONS 2. This question involves the implementation of a fitness tracking system that is represented by the StepTracker class. A StepTracker object is created with a parameter that defines the minimum number of steps that must be taken for a day to be considered active. The StepTracker class provides a constructor and the following methods. addDailySteps, which accumulates information about steps, in readings taken once per day activeDays, which returns the number of active days averageSteps, which returns the average number of steps per day, calculated by dividing the total number of steps taken by the number of days tracked The following table contains a sample code execution sequence and the corresponding results. Statements and Expressions Value Returned Comment (blank if no value) StepTracker tr StepTracker(10000); Days with at least 10,000 steps are considered active. Assume that the parameter is positive. new tr.activeDays () ; No…
1. Part 1: A point in the x-y plane is represented by its x-coordinate and y-coordinate. Design the class Point that can store and process a point in the x-y plane. Your class should contains the following methods. Default constructor without parameters that initializes the private data member to the suitable values Constructor with parameters sets the values of the instance variables to the values of the parameter. Accessor methods that return the values of the x-axis and y-axis. setPoint method which set the values of x-axis and y-axis makeCopy method that make a copy of a received object of type Point. getCopy method that returns a copy of the current object toString method that returns the object string isEqual that returns true if the current object is equal to the received object of type point distance, which receives two objects of type Point and returns the distance
