Create a class 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
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
