Develop a system by using Java programming language and object-oriented programming concepts for a hotel room reservation system. It should be a menu-driven stand-alone console application (No GUI required). No need to connect any database as well, but you may use file operations if required (not mandatory). Your system must have the following functionalities

o Register guests

o View available rooms

o Allocate a room for a guest

o Change/ delete room allocation for a guest

o Check-in to a room

o Checkout from a room

o Generate the bill
