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.

Part 1: Design a Class You’ll design a class named Car that has the following fields: yearModel—An Integer that holds the car’s model year make—A String that holds the make of the car speed—An Integer that holds the car’s current speed The class should have the following constructor and other methods: The constructor should accept the car’s model 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. Design appropriate accessor methods to get the values stored in an object’s yearModel, make, and speed fields. The accelerate method should add 5 to the speed field each time it’s called. The brake method should subtract 5 from the speed field each time it’s called. Create your class in a plain-text editor such as Notepad or TextEdit and save as a text file (*.txt). Part 2: Design a Program You’ll create both pseudocode and a flowchart to design a program that creates a Car object…

Define a class named Wall. The class should have two private double variables, one to store the length of the Wall and another to store the height ._Create adefault constructor that sets the length& height to 0, create a second constructor with input parameters for the of the data variables and third copy constructor.Add accessor and mutator functions to read and set both variables Add another function that returns the area of the Wall as double .Write program that tests all your constructors and functions for at least three different Wall objects
Make C# (Sharp): console project named MyPlayList. Create an Album class with 4 fields to keep track of title, artist, genre, and copies sold. Each field should have a get/set property. Your Album class should have a constructor to initialize the title (other 3 variables should default to null or 0). In addition, create a public method in the Album class to calculate amount sold for the album (copies sold * cost_of_album). You determine the cost of each album. Also create a method in the Album class to display the information. Print out of information should look something like this: The album Tattoo You by the Rolling Stones, a Rock group, made $25,000,000. In the main method, create 3 instances of the Album class with different albums, use setters to set values of the artist, genre, and copies sold. And then use getters to display information about each on the console.
1. RetailItem Class Write a class named Retailltem that holds data about an item in a retail store. The class should have the following fields: • description. It is a String object that holds a brief description of the item. • unitsOnHand. It is an int variable that holds the number of units currently in inventory. • price. It is a double that holds the item's retail price. Write appropriate mutator methods that store values in these fields and accessor methods that return the values in these fields. Once you have written the class, write a separate program that creates three RetailItem objects and stores the following data in them. Units On Hold Description Designer Jeans Jacket Price 40 34.95 12 59.95 Shirt 20 24.95

1- Design a class named Rectangle to represent a Rectangle. The class contains: • three variables integer data field named height, integer data filed named width and integer data filed named length. The default values are 1 for height, length, and width are 1.0 for each of them respectively. • A no-arg constructor that creates a default Rectangle. • A constructor that creates a Rectangle with the specified height, length and width. • A method named getVolume() that returns the volume of this Rectangle. (Volume = height * width * length) %3! 2- Write a test program called Test Rectangle that: • Creates two Rectangle objects: one object with height 11, length 5, and width 7, the other object with height 10, length 2 and width 6 • Display the volume of each Rectangle object.
Design a Ship class that has the following members:• A field for the name of the ship (a string).• A field for the year that the ship was built (a string).• A constructor and appropriate accessors and mutators.• A toString method that displays the ship's name and the year it was built.Disign a CruiseShip class that extends the Ship class. The CruiseShip class should have thefollowing members:• A field for the maximum number of passengers (an int).• A constructor and appropriate accessors and mutators.• A toString method that overrides the toString method in the base class. The CruiseShipclass's toString method should display only the ship's name and the maximum number ofpassengers.Design a CargoShip class that extends the Ship class. The CargoShip class should have thefollowing members:• A field for the cargo capacity in tonnage (an int).• A constructor and appropriate accessors and mutators.• A toString method that overrides the toString method in the base class.

Home Work 1 Create a class called circle that can read a circle radius, then calculate its area and perimeter? Circle Class Name radius: double Data member Circle() Constructors Circle(double) setRadius(double) getRadous(): double getArea(): double getPerimeter(): double Operations The first constructor will set the radius to 10 and the second one will set the radius as the user entry, make sure if the user entered a negative value for the radius your class will set it back to 10. In the main class create an object of your class, then let the user to enter the circle radius using the scanner then print your class data.
True or false: Just as a class can have multiple constructors, it can also have multiple destructors.
