Q No#1 (Employee Class) Create a class called Employee that includes three instance variables-a first name (type String), a last name (type String) and a monthly salary (double). Provide a constructor that initializes the three instance variables. Provide a set and a get method for each instance variable. If the monthly salary is not positive, do not set its value. Write a test application named EmployeeTest that demonstrates class Employee's capabilities. Create two Employee objects and display each object's yearly salary. Then give each Employee a 10% raise and display each Employee's yearly salary again. Guidelines: 1. Your Code must be fully commented. 2. The class name should be OOP vour roll number.

T/F: Instance variables are shared by all the instances of the class. T/F: The scope of instance and static variables is the entire class. They can be declared anywhere inside a class. T/F: To declare static variables, constants, and methods, use the static modifier.

True or False: 1. Data items in a class may be public. 2. Class members are public by default. 3. Friend functions have access only to public members of the class.

Dynamic Games Instructions: Write a class called Game that contains a video game’s name, genre, and difficultyLevel.  Include a default constructor and destructor for the class.  The constructor should print out the following message:  “Creating a new game”.  The destructor should print out the following message:  “In the Game destructor.”  Include appropriate get/set functions for the class. In main(), prompt the user to enter the number of games he or she has played in the past year.  Dynamically create a built-in array based on this number (not a vector or object of the array class) to hold pointers to Game objects. Construct a loop in main() that executes once for each of the number of games that the user indicated.  Within this loop, ask the user to enter the name and genre of each game.  Using a random number generator, generate a difficultyLevel between 1-10 (inclusive). Seed this random number generator with 100.  Next, dynamically create a Game object (remember that this…

Lab 2 – Designing a class   This lab requires you to think about the steps that take place in a program by writing pseudocode. Read the following program prior to completing the lab.   Design a class named Computer that holds the make, model, and amount of memory of a computer. Include methods to set the values for each data field, and include a method that displays all the values for each field.   For the programming problem, create the pseudocode that defines the class and enter it below. Enter pseudocode here

Using classes, design an online address book to keep track of the names, addresses, phone numbers, and dates of birth of family members, close friends, and certain business associates. Your program should be able to handle a maximum of 500 entries. Define a class addressType that can store a street address, city, state, and ZIP code. Use the appropriate functions to print and store the address. Also, use constructors to automatically initialize the member variables. Define a class extPersonType using the class personType (as defined in Example 10-10, Chapter 10), the class dateType (as designed in this chapters Programming Exercise 2), and the class addressType. Add a member variable to this class to classify the person as a family member, friend, or business associate. Also, add a member variable to store the phone number. Add (or override) the functions to print and store the appropriate information. Use constructors to automatically initialize the member variables. Define the class addressBookType using the previously defined classes. An object of the type addressBookType should be able to process a maximum of 500 entries. The program should perform the following operations: Load the data into the address book from a disk. Sort the address book by last name. Search for a person by last name. Print the address, phone number, and date of birth (if it exists) of a given person. Print the names of the people whose birthdays are in a given month. Print the names of all the people between two last names. Depending on the users request, print the names of all family members, friends, or business associates.

Please help me with this Java chapter 6 programming challenge. Thank you

java Assignment Description:   Write a class named Car that has the following fields: The yearModel field is an int that holds the car’s year model. The make field references a String object that holds the make of the car. The speed field is an int that holds the car’s current speed.   In addition, the class should have the following constructor and other methods. The constructor should accept the car’s year and make as arguments. These values should be assigned to the object’s yearModel and make fields. The constructor should also assign 0 to the speed field. Constructor: The constructor should accept no arguments. Constructor: The constructor should accept the car’s year as argument.Assign the value to the object’s yearModel.  No need to assign anything to the make and assign 0 to speed. Appropriate mutator methods should set the values in an object’s yearModel, make, and speed fields. Appropriate accessor methods should get the values stored in an object’s yearModel, make, and…

INVENTORY CLASS You need to create an Inventory class containing the private data fields, as well as the methods for the Inventory class (object). Be sure your Inventory class defines the private data fields, at least one constructor, accessor and mutator methods, method overloading (to handle the data coming into the Inventory class as either a String and/or int/float), as well as all of the methods (methods to calculate) to manipulate the Inventory class (object). The data fields in the Inventory class include the inventory product number (int), inventory product description (String), inventory product price (float), inventory quantity on hand (int), inventory quantity on order (int), and inventory quantity sold (int). The Inventory class (java file) should also contain all of the static data fields, as well as static methods to handle the logic in counting all of the objects processed (counter), as well as totals (accumulators) for the total product inventory and the total product…

Homework Assignment Chapter 10b Create a new Java Project named Chap10b Create a class named Vehicle that acts as a superclass for vehicle types. The Vehicle class contains private data fields for the number of wheels and the average number of miles per gallon. The Vehicle class contains getters and setters for the data fields. The Vehicle class also contains a constructor receiving integer parameters for the number of wheels and average miles per gallons, and a display() method that prints the required output (use get methods). Create two subclasses, Car and MotorCycle, that each extend the Vehicle class. Each subclass contains a constructor that accepts the miles-per-gallon value as an argument and forces the number of wheels to the appropriate value-2 for a MotorCycle and 4 for a Car. Use the superclass constructor to set the wheels and mpg data fields (use the super keyword). Write a UseVehicle class to instantiate one object of each subclass and calls the display method to print…
