Create a class MyTime which has the datamembers as follows: 1. hour: integer (1 to 12)2. minute: integer (0 to 59)3. second: integer (0 to 59)4. pm: bool variable. True means PM time and false means AM time. Implement a default constructor, a parameterized constructor and a copy constructor. Write set and get functions for all the four members of the class. Overload these operators: 1. Extraction operator >> : Prompt the user for hours, minutes, seconds and for am/pm and initialize the structure. Left operand istream object and right operand MyTime2. Assignment = : Assign the right object to the left object. Both operands are of type MyTime.3. Insertion << : Print the time in the format HH:MM SS PM. Left operand of type ostream and right operand of type MyTime. this in c++.
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.
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.

Hi can you assist me on the problem below for a class and a test class that conforms to the following specifications: 1. The name of the class is RightTriangle 2. 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…
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. Please note that,● A person has a name, address, phone number, and email address. A student has aclass status (freshman,sophomore, junior, or senior). 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.
Define a class Human with properties "first name" and "last name". Define the class Student inheriting Human, which has the property "mark". Define the class Worker inheriting Human with the property "wage" and "hours worked". Implement a "calculate hourly wage" method, which calculates a worker’s hourly pay rate based on wage and hours worked. Write the corresponding constructors and encapsulate all data in properties. Make a C# code in windows form. Upload screenshots of codes and outputs.
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; }}
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…
For this Programming Employee class should haveinstance variables to store the employee ID as an int and the employee’s department as a String.The Faculty class should have an instance variable to store the faculty member’s title (e.g., “Professor ofComputer Science”) as a String. The Staff class should have an instance variable to store the staffmember’s pay grade (a number from 1 to 20) as an int. Every class should have appropriateconstructors, accessors, and mutators, along with a writeOutput method that outputs all of the instancevariable values Note: code java
6. Write a class with a constructor that accepts a String object as its argument. The class should have a method that returns the number of b, c, d, f, g, h, and z in the string. Demonstrate the class in a program that asks the user to enter a string and returns the number of b, c, d, f, g, h, and z in the user string.
All vehicles used for transportation in the U.S. must have identification, which varies according to the type of vehicle. For example, all automobiles have a unique Vehicle Identification Number (VIN) assigned by the manufacturer, plus a license plate number assigend by the state in which the auto is registerd. Your task is to modify the Auto class below to override the equals method of the Vehicle class to test that the VIN and license plate number are identical.
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
