I am having difficulty completing this code.
• Validate the user course selection for registration against the given registration business
rules
The requirements of this application are as follows. The application is register students for
courses in a term of study.
The assumptions used by the application are:
• Student enters only integers to select courses for registration from a menu. No data type
validation of the user menu selection is checked or required
• Each course carries 3 credit hours
• The program terminates only when the student closes it
The program must follow these registration business rules:
• No registration of other courses not displayed by the program
• No registration more than once for the same course
• No registration for more than 9 credit hours (e.g. no more than 3 courses)
The application uses Java methods for its implementation. Students select from a menu of
courses for which they wish to register. The program then validates the user selection against
the registration business rules. If the selection is valid, the program prints out a confirmation
message. Otherwise, the program prints an error message. In all cases, the program also prints
out the current list of registered classes. The program terminates when the user does not want
to register for classes any more.
The program uses the Java method ValidateChoice() to validate the user integer menu selection
and acts accordingly. If the user selection is valid against the registration business rules, the
program displays a registration confirmation message to the student for the selected course.
Otherwise, the program displays an error message explaining the reason of the invalidation of
the selection. The application maintains and displays a current list of registered courses.
