Problem: Create a class called RoomOccupancy that can be used to record the number of people in the rooms of a

building. The class has the attributes:

numberInRoom the number of people in a room

totalNumber the total number of people in all rooms as a STATIC variable

roomCharges the charge for the nightly occupancy of the room, in dollars.

The class has the following methods:

addOneToRoom adds a person to the room and increases the value of totalNumber.

removeOneFromRoom removes a person from the room, ensuring that numberInRoom

does not go below zero, and decreases the value of totalNumber as needed.

getNumber returns the number of people in the room.

getTotal a static method that returns the total number of people.

In addition, the usual methods will be included, as usual:

At least TWO constructors a default/no argument constructor and an overloaded

constructor.

The accessor and mutator methods ( getters and setters ).

The toString method.

The equals method ( use the model used in the Person class)

The finalize method

The copy constructor

Write a client/test program to exercise the RoomOccupancy class.
