UML Class diagram:
A model of Class Diagram is the stationary structure of the system. It helps in determining
relationships among objects, classes, operations, and attributes (Goswami, 2012).
Figure 1 UML Class Diagram
Booking class in the image shown above is a parent class and Hotel class here is Child class. In
both the classes all the attributes are private and methods are public.
How long it took to create the whole program
I completed this whole program in 1 week. Firstly I have researched for this program in 1 day.
After that, I started to create a program.
Problems encountered:
 First I faced problem in JOptionPane. When I clicked on cancel button it was giving Null
pointer exception. I have solved this issue using exceptional handling.

 Second I faced problem in validation like customer name can't be blank, a number of
days can't be blank, maximum limit can't exceed but I have solved all these problems by
doing research.
