Textbook Question
Chapter 9, Problem 10E
Suppose that you are going to create an object used to count the number of people in a room. We know that the number of people in the room can never be negative. Create a RoomCounter class having three public methods:
- addPerson—adds one person to the room
- removePerson—removes one person from the room
- getCount—returns the number of people in the room
If removePerson would make the number of people less than zero, throw a NegativeCounterException.

Please answer JAVA OOP problem below:
Assume you have three data definition classes, Person, Student and Faculty. The Student and Faculty classes extend Person. Given the code snippet below, in Java, complete the method determinePersonTypeCount to print out how many Student and Faculty objects exist within the Person array. You may assume that each object within the Person[] is either referencing a Student or Faculty object.
public static void determinePersonTypeCount(Person[] people){
// Place your code here
}
Please answer JAVA OOP question below:
Consider the following relationship diagram between the Game and VideoGame data defintion classes.
Game has a constructor that takes in two parameters, title (String) and cost (double). The VideoGame constructor has an additional parameter, genre (String). In Java, efficiently write the constructors needed within the Game class and VideoGame classes.
Hint: Remember to think about the appropriate validation
