Use the documentation of the Java standard class libraries to find out about the inheritance hierarchy of the collection classes. Draw a -diagram showing the hierarchy
Below we have class diagrams with three classes for a simple java based parking management class. Use the classes below to write java code for classes :a parking observer class (that implements an observer pattern) , a transaction manager class and a parking lot class(subject to the observer). Use the class diagram and java class to implement it. You should use an observer pattern to implement your code.The main goal is to implement the following - 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
Using the class diagram in the image below, write a small report (200- 300 words) on how to create Money, Parking Charge, and Parking Office classes for an object-oriented parking system using java. Classes should demonstrate the use of java generics and collections.

The class diagram above shows class attributes (members) and methods (operations). Operations are denoted with a plus. The diamonds indicate an aggregation relationship between the connected classes. For example, a mailbox list can have one or many mailboxes. A Mailbox can have one or many messages. You will therefore need data structures container objects (lists) to contain these types of objects, as we have seen in previous exercises. All class attributes are private unless denoted otherwise and therefore must be accessed with constructors. getters, ord setters. Constructors are a preferred way to set class attributes. Constructors, setters, getters, and toString methods can be generated by IntelliJ. Check the IntelliJ documentation for how to use the Generate feature. Messages are simultaneously sent and received.

- Computer Science There are clearly some similarities in the implementations of Taxi and Shuttle that suggest use of inheritance to represent them. Introducing inheritance is the primary task of this assessment. -The Ezcab class, The Ezcab class maintains separate lists of taxis and shuttles and destinations with destination fares (you can hardcode destination fares). It has a lookup method that searches for a taxi/shuttle with a given ID. -The Taxi and Shuttle classes share some common attributes – location and destination. They also have some common methods – getLocation, getDestination, getStatus and setDestination. -Vehicle is the superclass of both Taxi and Shuttle. This class involves placing the common fields and methods into Vehicle and removing them from Taxi and Shuttle. -Modify Taxi and Shuttle class to indicate that it is a subclass of Vehicle.

- Your assignment for this course is to implement a beginner level Book Management System (BMS) in Java language. BMS contains 2 classes: Bookand BookList. The Book class has the following attributes: code: a String object, that hold the book’s code. title: a String object, that hold the book’s title. qua: int variable, that hold the number of books with the same code in the library. price: a double variable, that hold the book’s price. The BookList class contains only one data member: ArrayList<Book> t. When running the program display the menu as below:1. Input & add book(s) to the end.2. Display all books.3.
