Write a Java program that demonstrates inheritance and Polymorphism. For this purpose, you are required to create a parent class and 2 child classes as follows:

 

The main method is provided to you below. You are required to create two methods namely display() and getCount() in Driver.java file that would display all the results and count number of students and faculty in the given array respectively.

main method:

public static void main(String[] args)
{
Person persons[] = new Person[]{
new Student("Steve Jobs", "71 Simcoe Road", "111-111-1111", "steve@uoit.ca", "Freshman"),
new Student("BilL Gates", "100 College Creek", "111-121-1221", "bill@uoit.ca", "Sophomore"),
new Student("Elon Musk", "120 Simcoe Avenue", "786-111-7789", "elon@uoit.ca", "Freshman"),
new Student("Mark Wood", "2041 Davis Drive", "888-121-4111", "mark@uoit.ca", "Jnuior"),
new Student("Jack Ma", "68 Markham Road", "333-111-4444", "jack@uoit.ca", "Senior"),
new Student("Muhammad Khan", "29 Richmod Crescent", "111-000-2511", "muhammad@uoit.ca", "Freshman"),
new Student("Aleena Shah", "51 Simcoe Road", "666-777-8888", "aleena@uoit.ca", "Senior"),
new Student("Shakira Kin", "29 Toronto Road", "888-111-7771", "shakira@uoit.ca", "Junior"),
new Student("Laura Tim", "100 Prince Road", "999-000-1111", "laura@uoit.ca", "Freshman"),
new Faculty("Jasson Wood", "Davis Drive", "121-000-2222", "jasson@uoit.ca", "Assistant Professor"),
new Faculty("Tim David", "81 Toronto Yard", "121-222-8882", "tim@uoit.ca", "Associate Professor"),
new Faculty("Louis James", "131 James Avenue", "444-5552-4522", "louis@uoit.ca", "Assistant Professor"),
new Faculty("Tony Greg", "3331 King Avenue", "662-111-2999", "tony@uoit.ca", "Professor"),
new Faculty("Lizzy King", "881 Wilson Street", "777-666-0000", "lizzy@uoit.ca", "Associate Professor"),
new Faculty("Paula James", "101 Golden Road", "777-111-2000", "paula@uoit.ca", "Professor")
};
display(persons);
getCount(persons);
}

Expected Output:
