In order to prevent the mixing of non-object and object values, how may wrapper classes for non-object data types be used?

Please help me explain the below. They are on classes and objects - Data Encapsulation Definition - What does a class comprise of? - What are the different access specifiers and the difference between them - What are accessor and mutator methods - How do you create an object for a class - What is data hiding? - What is a constructor used for? - How do you write a constructor for a class? - What is function overloading and constructor overloading? - What is the use of the this keyword? - Passing objects to methods - What is the toString Method used for?

You have to implement program that compares graduate students based on their ranks. The design of the program is given in the following UML diagram:   • Student class: Base class that GradStudent extends. • GradStudent class: The objects from this class will be used for comparisons. • Rankable interface: Defines the implementation needed for  comparison. GradStudent implements this interface. • Test class will be used to get student information from the user and demonstrate the comparison of students.

Write a C#program that uses a class called ClassRegistration as outlined below: The ClassRegistration class is responsible for keeping track of the student id numbers for students that register for a particular class. Each class has a maximum number of students that it can accommodate.   Responsibilities of the ClassRegistration class: It is responsible for storing the student id numbers for a particular class (in an array of integers) It is responsible for adding new student id numbers to this list (returns boolean) It is responsible for checking if a student id is in the list (returns a boolean) It is responsible for getting a list of all students in the class (returns a string). It is responsible for returning the number of students registered for the class (returns an integer) It is responsible for returning the maximum number of students the class is allowed (returns an integer) It is responsible for returning the name of the class. (returns a string)   ClassRegistration -…
