A company wants their payroll system developed in OOP and they have approached you for the basic structure and functionality. They want an object with name and salary properties. The object should have a default constructor that initialises the properties to null and a parameterised constructor. The object should also have two accessors (methods of accessing the contents of a property), one for each property. They also want a method that will compare two objects and tell which has a better salary than the other.

Declare and implement an Employee class for the payroll system:
4.1 Declare a class that meets the scenario requirements. Ensure that the method that compares the two objects receives objects of the Employee class and returns an int.
4.2 Implement the class methods on the same code as the class declaration
4.3 Write a main function in the same code and test the payroll system. Use the parameterised
constructor to create the two objects and then test the method that compares the two and display a message that states which employee earns more than which employee.

- 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.

Your job at Train the Trainer is to put together the actual training materials. Right now, you are up against a deadline. The new object modeling seminar has a chapter on cardinality, and the client wants you to come up with at least three more examples for each of the four cardinality categories listed in Figure 6-16. The four categories are zero or many, zero or one, one and only one, and one or many. Even though you are under pressure, you are determined to use examples that are realistic and familiar to the students. What examples will you submit?What is the role of a normal constructor? Create the class Student, which must have a normalconstructor and at least 5 attributes
- What does the super keyword represents and where can it be used? Give an example of a superclass and subclass. Be sure to make all the instances variables of the super class private. Include at least one constructor in each class and ensure that the constructor of the subclass calls the constructor of the superclass. Also include a toString method in both classes that returns the values of the instance variables with appropriate labels. Ensure that the toString method of subclass calls the toString method of the superclass so that the string returned contains the values of all the inherited instance variables.What is the role of a normal constructor? Create the class Student, which must have a normal constructor and at least 5 attributes. Note: The attributes must include all the details mentioned in the scenario and others of your choice. The marks of the student in different modules must be stored using arrays. b. Explain the benefits of encapsulation in Object Oriented Programming. Include proper methods for setting and getting the attributes of the class Student. c. In the class Student, create a method for each of the following results using the array concept and any type of loop: i. The total or average mark of the student in each module. ii. Finding the list of modules that the student has passed or failed in that semester. iii. Finding the highest or lowest mark of the student in all assessments. d. Draw the tracing table that shows an example of execution of any of the previous methods. e. Create details and at all the results found in task 2.c by calling the respective methods. a…What is the role of a normal constructor?

- Write the program of object oriented programming c++. Declared Rectangle(Data Members: Length and width) as a friend class of Square(Data Member: int side). Thus now, all the functions of Rectangle can directly access any private member of Square.In the main function, the first statement created an object 'square' of the class Square, thus calling its constructor and assigning 5 to its data member side.The second statement in the main function created an object 'rectangle' of the class Rectangle.In the third statement, 'rectangle' called the function shape() with the object of the class Square passed as its argument. In the 'shape()' function, the value of 'side' (private data member of Square) was assigned to length and breadth. The fourth statement called the function 'getArea' of the class Rectangle.For this portion of the assignment you will need to create the Employee class * based on the instructions in the API and have implemented the Equals method for that class. * * There is one parameter being passed as to this method that you will use as part of your solution:* An Employee object reference with the identifier testEmployee* * 1) Instantiate an instance of the Employee class using the default constructor and * assign it to an object reference with the identifier defaultEmployee* * 2) Instantiate an instance of the Employee class using the alternate constructor, * passing the following arguments:* name: "Keanu Reeves"* ID: 10010* salary: 78000.00* Assign the instance to an object reference with the identifier keanuEmployee* * 3) Declare a variable of type Employee with the identifier excellentEmployee and assign it * a reference to the same object that is being referenced by the keanuEmployee object reference. * 4) Construct a selection statement that tests if testEmployee is…question 1 C++: Write a class whose objects each represent a piece of chewing gum.
