Basic Class - State Data reate a StateData class with the following methods: __init_ ote: is two underline characters (dunder). he __init___ method should have the parameters self, name, abbreviation, region, and population and should store the name, abbreviation, region, and population as attributes. he ___str___ method has the parameter self and should return the state's name. he displayState method has the parameter self and should print formatted state data as shown below. est the class by creating an instance of the class (instantiating) called s1 with the following data: "California", "CA", "West", 39250000. Print your state object (this will call the_str_method). Then call displayState. This test code should be after your class code - don't worry about call: om main. ample Execution Results: _str_displayState.

For this assignment *c++ & no ifstream, you need to build a class that contains basic information about students and courses that have those students on the roster. You also need to build a menu that supports basic CRUD functionality for those courses. The requirements are as follows: The student class should contain the following data about a student: Name (dynamic char array) Classification (char) Major (dynamic char array) StudentId (can be an int or a dynamic char array) The course class should contain the following data about a course: Course Name (dynamic char array) Course Code (char array of size 7) Location (char array of size 10) Roster (dynamic student array) The menu program should act as a driver program that manages a dynamically allocated array of courses and allows the user to: Add a course to the list Add students to a course Update a course to change any of the data above including edits to students or adding/removing students from the roster List courses…
Create a class that represents an employee. This class will have three constructors to initialize variables. If the constructor doesn't provide a parameter for a field, make it either "(not set)" or "0" as appropriate.

Create AutomaticCar class that shall have private model, year, speed and gear attributes. Encapsulate complete state and expose the state for read/write (where it makes sense and needed). As its automatic car, so other shall not be able to update the gear attribute directly. The gear would auto change based on speed and other parameters (defined below). The speed range for different gears is (gear : speed-range) 0:0 1:1-100 2:101-200 3:201-300 4:301-400 5:401-500. The speed should not be updated if a -ve value is passed to its set method, in such cases, it shall print an appropriate error message. If car's earlier speed was 50 and set method is called with argument 20, the car speed would become 20, not 70. Please note, same method would be used to increase and decrease the speed, depending on whether the earlier speed was lower or higher as compared to new value passed. Here are some further points/rules that you must implement: Make LuckyRacer class, in its main method, create 5…

Consider a class named Graduate Course that includes Three data members i.e. o courselD (e.g. CS2133), o courseName (e.g. OOP), O creditHours (e.g. 3 or 4), and o courseFee (e.g. Rs. 10,000). A parameterized constructor to initialize data members with values specified by the user Derive a class named Research Course from Course class, which contains An additional data field named experiment Fee A parameterized constructor to initialize its own data member along with data members of the base class inherited in derived class Research Course class also contains a member function named setExperiment Fee to modify the value of its own data field A function named display to show the values of its own attribute along with the attributes of its base class A function named totalFee to display the value of aggregated fee (course fee+ experiment fee) for a particular course object Implement both classes and in the main() function, create an instance of ResearchCourse class.

I need the source code for this question 4 in Java. Please provide an explanation for the methods provided. Client Class:The client program should read the input data from the user (or the method with hardcoded inputs)and use the Change class to store the data entered. This data should be stored in a Change classobject. You will need a data structure to store the Change class objects according to the number ofpersons entered. Thus, you are to utilize an array of Change objects. Do not use ArrayList for thisassignment It should be noted that it is possible to have the same name entered numerous times, but the coinvalues for such repetitions could be different. When the name is the same, it would mean the sameindividual, and your program should add up the coin amounts to obtain a total amount for thatindividual; this should be performed before computing the change to be given. Note that in thisscenario, the total amount for an individual may end up being over 100, 200, 300, or more cents…
C++ OOP Create a Student class, where attributes associated with each student are name, registrationnumber, father name, degree and department. All attributes should not be accessed directly.One can view the details of all students. Note student attributes can not be changed by anymeans after initialization. (Hint use constant objects).In student class maintaining student count means your program could be able totell the count of student objects created. (User static counter variable)
QUESTION 8Consider this scenario, You use direct access to private fields inside a class, you want to refactor the code by creating a getter and setter for the field, and use only them for accessing the field. Which refactoring technqiue I'm describing?1. Move Function2. Extract variable3. Combine Functions into Class4. Encapsulate Variable
