Question

for the following classes you are required to use private properties and include corresponding getters and setters…

Create an advanced enumeration to represent the months. Each enum should come with a friendlyName, shortName, daysInMonth, isLeapYearMonth, the zodiacSign, the zodiacStartDay and zodiacNextMonthEndDay

Tester

Properties

(ConcurrentHashMap()) rentals (Key is the apartment’s apartmentId)

Apartment

Properties

(string) apartmentId, address

(ConcurrentHashMap()) renters (Key is the renter’s renterId)

2 Constructors: Accepts: apartmentId, and address

Accepts: RandomAccessFile

Methods:

addRenter(Renter r)

save(RandomAccessFile raf), load(RandomAccessFile raf)

RenterProperties

(string) renterId, name

(ConcurrentHashMap()) items (Key is the item’s itemId)

2 Constructors: Accepts: renterId, and name

Accepts: RandomAccessFile

Methods

addItem(Item i)

save(RandomAccessFile raf), load(RandomAccessFile raf)

ItemProperties

(string) itemId, name

2 Constructors: Accepts: itemId, and name

Accepts: RandomAccessFile

Methods

save(RandomAccessFile raf), load(RandomAccessFile raf)

In the App class you should populate your tree of data starting with 3 Apartments, each rental has 4 renters, and each renter has 3 items. Save the data by calling the save for each apartment. This should cascade down the tree. Clear the rentals ConcurrentHashMap and then reload the entire structure (code below) and print the list

while(raf.getFilePointer() < raf.length())

Apartment a = new Apartment(raf);

rentals.put(a.apartmentId, a);

}

ITS A JAVA PROGRAM,AND THE PICTURE IS FOR "ADVANCING ENUMERATION"

Answer 2 : Tester.java
-----------------------------
package task2018;
import java.util.concurrent.ConcurrentHashMap;
public class Tester {
private ConcurrentHashMap<String, Apartment> rental = null;
private Tester() {
rental = new ConcurrentHashMap<String, Apartment>();
}
}
------------------------------------------
Answer 3:  Apartment.java
------------------------------------
package task2018;
import java.io.RandomAccessFile;
import java.util.concurrent.ConcurrentHashMap;
public class Apartment {
private String apartmentId;
private String address;
private ConcurrentHashMap<String, Renter> renters = null;

public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public RandomAccessFile getFile() {

Answer 5 : Item.java
-------------------------------
package task2018;
import java.io.RandomAccessFile;
public class Item {
private String itemId;
private String name;
private RandomAccessFile file = null;
private Item(String itemId, String name) {
super();
this.itemId = itemId;
this.name = name;

Description
--------------------
1. As per the chegg policy, As an expert We need to answer first four question so please find the answer for first five question above as all the five question are related to class definition and for rest of the question you need to draft the same question again with updated code so that chegg expert provide you the best solution.

All the classes are compliable. Please let me know if you found any difficulties to use them.

2. I have provided all the class definition which includes constructor, properties , methods like properties setter,getter method and save and load.
3. For save and load method implementation you need to submit the question again as suggested above.

Thanks
