mestny [16]

Answer:

Explanation:

The following Python code creates all of the necessary functions in order to request and validate all of the inputs from the user. Once everything is entered and validated it calculates the total fee and outputs it to the user. Also calls the entire class at the end using a test variable...

class Customer:

   library_card = 0

   patrons_name = ""

   patrons_address = ""

   type_of_book = ""

   book_title = ""

   days_overdue = 0

   fee = 0.0

   book_list = ['paperback regular', 'paperback best seller', 'magazine', 'hardcover']

   def __init__(self):

       self.library_card = self.get_library_card()

       self.patrons_address = input("Patron's Address: ")

       self.book_title = input("Book Title: ")

       self.type_of_book = self.get_type_of_book()

       self.days_overdue = float(self.get_days_overdue())

       self.calculate_total()

       print("Your total Fee is: " + str(self.fee))

   def get_library_card(self):

       library_card = int(input("Enter 4-digit library card number: "))

       if (type(library_card) == type(0)) and (len(str(library_card)) == 4):

           return library_card

       else:

           print("Invalid Card number:")

           self.get_library_card()

   def get_type_of_book(self):

       type_of_book = input("Type of Book 1-4: ")

       if (int(type_of_book) > 0) and (int(type_of_book) <= 4):

           return int(type_of_book)

       else:

           print("Invalid Type")

           self.get_type_of_book()

   def get_days_overdue(self):

       days_overdue = input("Number of Days Overdue: ")

       if int(days_overdue) >= 0:

           return days_overdue

       else:

           print("Invalid number of days")

           self.get_days_overdue()

   def calculate_total(self):

       if self.type_of_book == 1:

           self.fee = 0.20 * self.days_overdue

           if self.fee > 8:

               self.fee = 8

       elif self.type_of_book == 2:

           self.fee = 0.50 * self.days_overdue

           if self.fee > 15:

               self.fee = 15

       elif self.type_of_book == 3:

           self.fee = 0.25 * self.days_overdue

           if self.fee > 5:

               self.fee = 5

       else:

           self.fee = 0.30 * self.days_overdue

           if self.fee > 23:

               self.fee = 23

test = Customer()

The name of a .java file should ______________________________. Always match the name of the Class inside Should always start wi
natita [175]

Answer:

The name of a .java file should <u>always match the name of the class inside.</u>

Explanation:

In Java programming the program written in code editor is first saved with .java extension. The name of this .java file should be same as that of  the class declared inside the file.

This .java file is then compiled and  converted to .class file which contains the java bytecode. This bytecode can then be executed by java virtual machine(JVM).

However it is not always necessary that name of .java files should be same as that of class inside it. The name should be same only when the class inside is declared as public.

In case it is not declared as public one can name .java file different than the actual class name.
