billBook
-invoiceNumber: String
-visitDate: String
-patientName: String
-paid: boolean
-bills: bill[]
-doctor: String
+bill(all parameters)
+Setters/getters methods(if
needed)
+printInvoice(): void
+billBook(doctor:String,capacity:int)
+Setters/getters methods (if needed)
+addBills(): void
+payBill(invoiceNumber: String): int
Implement the class bill:a. Write the constructor that takes as parameters all data fields except the paid value. A
bill object is by defauld not paid.
b. The printInvoice() method should output the following information:
The invoiceNumber, the visitDate, the name of the patient name
A message “The bill is paid” or “The bill is not paid” according to the value of the field paid.
2. Implement the class billBook using the above UML:
a. Write the constructor that takes as parameters the name of the doctor who has
examined the patient and the capacity which represents the size of the array bills.
b. Write the method addBills that reads the information of bill objects from the user,
creates the objects, and fill them into the array billBook.
c. Write the method payBill that:
It takes as parameter the invoive number.
Searches for the bill if available. If the bill is found, and it is not paid then the paid
value is updated to true. The method returns 1.
If the bill is not found, the value -1 is returned.
3. Write an application (Driver class) in which you:
- Create a billBook object of capacity 5. Read the doctor’s name from the user.
- Call the method addBills.
- Allow the user to pay a bill of his/her choice. Ask the user to enter the invoiceNumber
of as many bill objects as he/she wants. If the bill is not found, then a “The bill is not
found” message should be displayed. Assume the invoice numbers are different.
- Find the number of paid bills in the array.
