Question text
Determine whether the ff hypotheses about a computer
program
• There is an undeclared variable or there is a syntax
error in the first five lines.
• If there is a syntax error in the first five lines, then there
is a missing semicolon or a variable name is
misspelled.
• There is not a missing semicolon.
• There is not a misspelled variable name.
lead to the conclusion
• There is an undeclared variable.
Let the following symbols represent the corresponding
statements:
uv - There is an undeclared variable.
se - There is a syntax error in the first five lines.
ms - There is a missing semicolon.
vm - There is a misspelled variable name.
Thus, in symbolic form, we have to show whether the
argument below is valid:
uv V se
se → (ms V vm)
~ ms
~ VM
... uv
Question
Using Java programming language write a program to manage a hotel with 24 rooms;10 rooms are Executive, with price Gh ₵ 2500.00 per night,7 rooms are Chalets, with amounts Gh ₵ 1500.00 per night7 rooms are Ordinary, with amount Gh ₵ 500.00 per night
The program should allow customers to book for rooms for a number of nights, and update the number of empty rooms available for each category when a customer has paid fully and has checked-in; also update the number of empty rooms available when customer checks-out.Customers should make bookings with their first names, telephone number
A customer should be prompted to know if a room is booked (meaning a another customer has booked it but has not paid fully, or has not checked-in)
A customer should be prompted to know if a room is occupied (meaning a booked room has been fully paid for, or the customer has checked-in)
A customer should be prompted to know if a room is available (meaning a room has neither been booked nor…
