Justify the need for accessors for private types rather than public kinds using only three phrases.
Question 01: Implement the following UML class diagram.

Suppose that the application requires you to model students. A student has a name and an address. You are required to keep track of the courses taken by each student, together with the grades (between 0 and 100) for each of the courses. A student shall
Abstract data types In a paragraph, describe a real-world abstract data type that you can think of. Some of the examples we discussed in lecture were a mechanical throttle or a car's engine.
An Abstract Data Type (ADT) is a data type that contains just variables, without information about their values. ADTs have many benefits. By reducing the issue to its simplest parts, it becomes easier to solve.
Implement a nested class composition relationship between any two class types from the following list: Advisor Вook Classroom Department Friend Grade School Student Teacher Tutor Write all necessary code for both classes to demonstrate a nested composition relationship including the following: a. one encapsulated data member for each class b. inline default constructor using constructor delegation for each class c. inline one-parameter constructor for each class d. inline accessors for all data members e. inline mutators for all data members

This question concerns environments and scope chains. We will use the following definition for environments: EmptyEnvironment : empty environment Extend(id, value, old_env) : extend old_env by binding variable named id to value. • ExtendRec(rec_function_name, formal_param, body_expr, old_env): a recursive scope chain with name of function, formal parameter, body of function and the old environment. Consider a series of environments og,...,o3 below and answer the questions following each. • og : EmptyEnvironment What is the value of lookup(x, oo)? (Type your answer. No explanations please). • q1 : Extend(y, 40, Extend(2, 20, o0)) What is the value of lookup(x, 01)? (Type your answer). • o2 : Extend(x, 75, o1) What is the value of lookup(x, og)? (Type your answer). • o3 : ExtendRec(f, 0, e, o2) What is the value of lookup(x, as)? (Type your answer). What is the value of lookup(f, og)? (Choose the correct answer).

How does the static data member of a class differ from a non-static data member? Give a real-worldscenario in which a static data member might be useful.

Indications:Person is an abstract class containing the abstract method Print().In Teacher and Student the method print() will print the information of either Teacher or Student.Write the class university corresponding to the following UML diagram. It contains three attributes.Tab is an array of Person. sizeTab is the size of Tab. The attribute n represents the number of elements added to the tab. When the tab is empty n is equal to 0.The constructor University(sizeTab) will initialize the different attributes and allocate the memory to the array Tab.addPerson(p:Person) will add the new person to Tab. The method printAll() will print all the information of the Persons inside Tab.Write the main method. Create three Teacher and three Student and add them to University Object and print them all.
An unspecified data type can be used for both the parameters and the return type just for abstract classes (because they can not be instantiated) just for the signature of a method (i.e., the parameters) O just for the non-signature parts of the method (i.e., the return type)
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.
