Did You Pushed Further?

Have a look at properties (Lab 8 - Part II)
Have a look at the variety of UML diagrams (Lab 9 - Part III)
Know more about the Math class (Lab 10 - Part II)
Rework previous problems (Lab 8 - Part II, Lab 10 - Part II, Lab 11 - Part II)
Design a static class (Lab 13 - Part IV)
Have a first look at for statement (Lab 14 - Part IV)
Discover how strings are ordered (Lab 14 - Part IV)

Part II - Working on Problem-Solving

Download, extract, compile and execute Course.zip. Then, read the code, and make sure you understand everything in it: the role of the static attribute, the difference between the two constructors, the branching in the constructor that takes two arguments. Then, do the following:

Write a ToString method that returns
1. The name of the student, followed by
2. “is registered for section A.” of the student is in section A, “is on the waiting list.” if the student is on the waiting list.
Test your method in the program, printing the information about various students.
Your next step will be to open a second section:
1. We want to have a section B, with 4 seats available. Implement the existence of this section with a static attribute.
2. The constructor that takes one argument should now assign the student to section A if there is room available, to section B if section A is full but section B isn’t, or to the waiting list if both sections are full.
3. Think about how you should change the constructor that takes two arguments, and implement what seems to be logical. For instance, if a student wants to enroll in section B, but section B is full and section A isn’t, should the student go to section A or be on the waiting list?
4. Finally, correct your ToString method, so that the string returned describes accurately the section the student is enrolled in.

Bonus: There is an inconsistency in the constructor that takes two arguments, can you spot it? What will happen if the user gave a code for the section that isn’t 'A' or 'a', and section A is full? Can you fix this?
