Textbook Question
Chapter 8, Problem 1E
Consider a program that will keep track of the items in a school’s library. Draw a class hierarchy, including a base class, for the different kinds of items. Be sure to also consider items that cannot be checked out.
Expert Solution & Answer
Explanation of Solution
Class hierarchy for school library:
- In the above diagram, “Library” is the base class, “Book”, “Audio visual material”, and “Periodicals” are the derived classes of the “Library”.
- The “Reference Book”, and “Text Books” are the derived classes of the “Book” class.
- The “Magazine”, and “Newspaper” are the derived classes of the “Periodicals” class.
- Here, every book must be checked out.

Write out the outer wrapping of a class called Person. Remember to include the curly brackets that mark the start and end of the class body, but otherwise leave the body empty.
Create a Java Project (with a class and a test class) to represent some real-world entity such as a
technology item (TV, Fan etc), an animal, a person, a vehicle, etc. In our class, we have already
seen example classes such as Circle, Student, Rectangle, TV etc.

- For a parking management system, use the Observer pattern to implement this interaction using Java and implement the three classes mentioned below. Implement a ParkingObserver that has the role of the Observer. The Observable classes (Subjects) will be the ParkingLots. It would be helpful if the notify method in the subjects (and update method in the observers) took a parameter, perhaps an object of type ParkingEvent, which could have fields including the lot, timeIn, timeOut (if relevant), and permit. The ParkingObserver should register with each ParkingLot and receive the messages. Once a car enters (in an entry-scan only lot) or leaves (in an entry-scan and exit-scan lot), then the ParkingObserver will be updated, and then can register the charge with the parking system via the TransactionManager’s park() method. Based on these requirements you should implement three actor classes in this interaction using java: TransactionManager, ParkingObserver and ParkingLot. 1.

There is a maximum capacity to the number of gold coins a leprechaun can store at any given time (the pot they store them in can only hold so many). The pot also holds a current amount. What does the LeprechaunGold object need to remember? Those are the instance variables. Provide a constructor that takes the maximum capacity as a parameter. The constructor initializes the instance variables (two of them). Provide methods public int getCapacity() - gets the maximum capacity public int getAmount() - gets the number of coins in the pot public void donate(int coins) - simulates making a donation public void save(int coins) - simulates adding more coins to the potarrow_forwardThis implementation makes so much more sense, however, the LineItem class I have to go off of is a tad bit different.

Since frogs should not eat their kind, a function of "isEatable" should also beimplemented in decision making.
