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
In a shopping cart, there are various items, which can either belong to the category of household items or electronic items. The following UML diagram illustrates the relationship between items, household items, and electronic items.
//Implementation Class
public class ShoppingCart{
public static void main(String[] args){
final int MAX_ITEM = 50;
Item cart = new Item[MAX_ITEM];
addItem(cart); // populate the item array
printItem(cart);
}
}
Considering that all the data definition classes and the implementation class are complete, which of the following Object-Oriented Programming (OOP) concepts do you need to use in the above context?
i) Polymorphism
ii) Method Overloading
iii) Method Overriding
iv) Dynamic Binding
v) Abstract Class
Explain, using course terminology, how you would use any of the above concepts to model the given scenario.

- Develop a C++ program that execute the operation as stated by TM for addition of two binary numbers (see attached image). Your code should receive two binary numbers and output the resulting sum (also in binary). Make sure your code mimics the TM operations (dealing with the binary numbers as a string of characters 1 and 0, and following the logic to increase the first number and decreasing the second one. Try your TM for the following examples: 1101 and 101, resulting 10010; and 1101 and 11, resulting 10000.arrow_forwardI need to define and discuss the uses of one monitoring or troubleshooting tool in Windows Server 2019. thank youarrow_forwardI would likr toget help with the following concepts: - Windows Server features - Windows Server versus Windows 10 used as a client-server networkarrow_forward
