Please solve PART TWO, thank you!

Part I:

1. Draw a UML representation for the hierarchy of the above-mentioned classes. Your representation must also be accurate in terms of UML representation of the different entities and the relation between them. You must use a software to draw your UML diagrams (no hand- writing/drawing is allowed).

2. Write the implementation of the above-mentioned classes using inheritance/composition and according to the specifications and requirements given below:

You must have 3 different Java packages for the classes. The first package will include the Address class. The second package will include the WebPageAddress, EmailAddress and the TelecomAddress classes. The third package will include the GeographicAddress, PostOfficeBoxAddress, and GeneralDeliveryAddress classes.

For each of the classes, you must have at least three constructors, a default constructor, a parameterized constructor (which will accept enough parameters to initialize ALL the attributes of the created object from this class) and a copy constructor. For instance, the parameterized constructor of the TelecomAddress class must accept 6 parameters to initialize the international direct dialing, the national direct dialing, the area code, the number, the extension, and the physical type.

An object creation using the default constructor must trigger the default constructor of its ancestor classes, while creation using parameterized constructors must trigger the parameterized constructors of the ancestors.

For each of the classes, you must include at least the following methods: accessors, mutators, toString() and equals() methods (notice that you are always overriding the last two methods).

The toString() method must return a clear description and information of the object (For example: This email address dave.velop@cleancode.app is valid from 2018-01-31 to 2021-12- 31 and therefore still usable today).

The equals() method must first verify if the passed object (to compare to) is null and if it is of a different type than the calling object. The method would clearly return false if any of these conditions is true; otherwise the comparison of the attributes is conducted to see if the two objects are actually equal. Two objects are equal if all the values of all their attributes are equal.

For all classes you must use the appropriate access rights, which allow most ease of use/access without compromising security. Do not use most restrictive rights unless they make sense!

When accessing attributes from a base class, you must take full advantage of the permitted rights. For instance, if you can directly access an attribute by name from a base class, then you must do so instead of calling a public method from that base class to access the attribute.

3. Write a driver program (that contains the main() method) that would utilize all of your classes. The driver class can be in a separate package or in any of the already existing packages. Besides the main() method, create a method called traceObsoleteAddresses(). This method takes four parameters, an array of Addresses, and three integer values representing a date (YYYY, MM, DD). The method must search in the array of Addresses and display all addresses that are/were obsolete in comparison the passed date. For example, if the passed date is 2021, 02, 15 and an Address has date limits of 1998-05-21 and 2010-10-03, then this Address is obsolete. Again, you should notice that Addresses can have future dates (yet to become effective). For instance, if the passed date is 2021, 02, 15 and an Address has date limits of 2021-10-18 and 2023-4-20, then this Address is also obsolete in relation to the passed date.

4. In the main() method you must: Create various objects from the 6 classes, and display all their information (you must take advantage of the toString() method). Some of them must be obsolete addresses, limiting their usage only between validFrom and validTo dates.

• Test the equality of some of the created objects using the equals() method.

• Create an array of 15 to 20 these address objects (HINT: Do you need to add something else to the classes described above? If so; go ahead with that!) and fill that array with various objects from these classes (each class must have at least one entry in that array).

Call the traceObsoleteAddresses() method with the array created above, along with any date of. The method should trace and display all information of all obsolete Addresses along with their location (index) in the array.

Part II

In that part, you need to modify/expand the implementation from Part I as follows: 1. In the driver program, you need to add another static method (add it above the main() method),

called copyAddresses. The method will take as input an array of these objects (the array can be of any size) and returns a copy of that array. That is to say, the method needs to create an array of the same length as the passed array, copies all objects from the passed array to a new array, then returns the new array. Your copy of the objects will automatically depend on the copy constructors of the different listed classes. You must consider the following restrictions: Do NOT attempt to explicitly find the exact type of the objects being copied, do NOT attempt to find the object type inside the copy constructors and Do NOT use clone().

2. In the driver program, create an array of 15 to 20 objects (must have at least one from each of the classes), then call the copyAddressObjects() method to create a copy of that array.

3. Display the contents of both arrays, then add some comments indicating whether or not the copying is correct. If not; you need to explain why it has not been successful or as you might have expected.

General Guidelines When Writing Programs

Include the following comments at the top of each class you are writing.

// ----------------------------------------------------- // Part: (include Part Number) // Written by: (include your name(s) and student ID(s)) // ----------------------------------------------------- 

• Use JavaDoc to create the documentations of your program. Use appropriate comments when needed.

• Display clear prompts for the user whenever you are expecting the user to enter data from the keyboard.

  All outputs should be displayed with clear messages and in an easy to read format. End your program with a closing message so that the user knows that the program has terminated.
