- For the Employee class, create the following: A private String instance variable m name. A private string instance variable m department. A constructor that takes two parameters (in the order of name, department) and sets the instance variables. A getter method for m name and a getter method for m department. An abstract string method named getPaycheck that does not take any parameter.Create 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…Write code for the InternetThing class to complete: a. A constructor that accepts a manufacturer and a serial number as its parameter. This constructor performs the following actions: i Store the serial number as a string ii Set a unique id number as an integer(hint- use the nextId). iii Set the IP address to the value “192.168.0.”+idnumber iv Set a local representation of a the power used in mW to the integer 1. v Set the password to “admin”. vi Prints the value “Created ”+ the result of the toString() method after assigning all instance data. vii Increment the number of things on record. b. Accessors for all private variables – Ensure the accessors for id, password and powerUse are named getId(), getPassword() and getPowerUse() c. A method setPassword that accepts a string argument and sets the instance password to the argument. All instance variables, except the password, should be private. The password should be protected.

The class has member variables base and height 3. The class has a constructor that initializes base and height 4. The class has accessors and mutators for base and height 5. The class has a toString method that produces String representation of a RightTriangle like the following example for a triangle with base 12 and height 10. Base : 12 Height 10 6. The class has a method called findArea to compute the area of the right triangle. Here is a suggested implementation. public double findArea() { return 0.5* this.base*this.height; } 7. The class using proper naming conventions Write a test class called RightTriangleTest that conforms to the following: 1. Create an object with base = 10 and height = 20, for example myTriangle. 2. To print the toString for myTriangle. 3. To print the area of myTriangle. System.out.println(“The…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; }}Implement the following using JAVA: a.Design a class named Person and its two subclasses named Student andEmployee. b.Make Faculty and Staff subclasses of Employee.

You can define the status as aconstant.● An employee has office & salary.● A faculty member has office hours and a rank.● A staff member has a title. c. Draw a UML diagram of the system.
- I hope you are fine, I want the code for this class .. Even if it is a small part of it, please, I want it for necessity, thanksIn 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:…For the StudentWorker class, create the following: A private int instance variable m hours. A private int instance variable m A constructor that takes four parameters (in the order of name, department, hours, hourly wage). It should use the parameters for hours and hourly wage to set the m_hours and m hourlyWage instance variables and then explicitly call the parent class constructor using the super keyword and pass in the two other parameters. hourlyWage. A getPaycheck method that implements the same method in the Employee class. It calculates the paycheck amount (m hours × m worker's paycheck as a string in the following format (Note that the three fields are hourlyWage) and returns the student separated by a hyphen, represented by the minus character. Do NOT add spaces before or after each hyphen. There are no commas in the number.): Optimus Prime-Computer Science-$1200
- PLZ help with the following: In JAVA ABC Company helps its clients to find a quick and easy analysis for better investment decisions. It would like to include the ways to calculate the evaluated price and investment analysis for the two types of property, ‘Condo’ and ‘single-family home (SFHome). Implement the class property based on the following specification. The class has - Instance variables: ▪ address that holds the address of the property and is of type string. ▪ ZoneCode which is an integer indicating the zone of the property. (possible values 1, 2, and 3) ▪ NoOfBedrooms that holds the number of bedrooms in the property. ▪ YearofConstruction an integer to hold the year of construction ▪ RiskFactor which is a float number in the range(0.0,1.0) for the risks related to investments in real estate market. ▪ Type indicates if the type of the property is a Condo or a SFHome. - At least three constructors, a default constructor, a parametrized…Define a class named Employee. This class should extend the Person class from the previous question. The class should have a constructor, which takes the name, age, employer (String) and salary (int) as parameters (in that order). The first two parameters should be passed to the constructor of the superclass and the value of the last two parameters should be stored in instance variables. The class should define the methods, getSalary which returns the salary of the employee and getEmployer which returns the name of the employer. Any methods from the previous question that need to be overridden should be overridden! Use super and instanceof as appropriate. I.e., for the following methods you should be able to call the method in the superclass for specific situations (e.g. the compareTo method in the superclass can be called if you receive anything other than an Employee, and this also holds for the equals method). The toString method only needs to append details and as such can also…An airport van shuttles passengers between the terminal and the parking garage. After 4 trips, the tank is empty, and the van needs to drive to the gas station. After it has been refilled, it will drive to the terminal. The behavior of the car depends on two states: its location (terminal, garage, or gas station), and the tank level (empty or not). Complete the following class. The constructor yields a van in the garage with a full tank.
