+# Hotel-Management-OOP-Project
+
+This is a Hotel Management tool which can be used to manage
+activites like storing customer details, booking rooms of four different types, ordering food
+for particular rooms, unbooking rooms and showing the bill. It can also be used to see
+different room features and room availibility. It is a menu driven program and it runs until
+the user exits. File handling has been used to store the current status of the
+hotel(customer details, booked rooms, food ordered) in a file once the program exits so
+that when we restart the program, the old details are not lost. The program reads the file
+when it restarts to know the previous status of the hotel. Writing of file has been done in a
+separate thread as it can be done parallely. User defined exception is thrown if the user
+tries to book an already allotted room. Exception handling is properly done to deal with any
+kind of unexpected exception.
+##### Topics Covered-  
+Classes and Objects, Inheritance, File Handling with Objects, ArrayList, implementing
+Interface, User defined exception and Exception handling.
