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
