Download the following files: Inheritance Demo java Person.java Student.java Undergrad.java Examine the code and run the program (InheritanceDemo) to see how it works. Programming Activity 1 Create a new class, Lecturer, that extends Person. A Lecturer is a Person with a stipend (a double value representing how much that lecturer will be paid for teaching a course). Create a constant for the default stipend (10,165). Create two constructors for the class: one accepts a name and stipend amount; the other accepts just a name and uses the default stipend. Include any appropriate getters/setters. Programming Activity 2 Give your Lecturer class a writeOutput method, which produces output like this: Name: (name) Stipend: $(stipend) Programming Activity 3 Test your Lecturer class by adding the following code to main in Inheritance Demo: Lecturer 11 = new Lecturer ("Zachary"); Lecturer 11 - new Lecturer ("Wilhelmina", 11.writeOutput(); 12.writeOutput(); pause(); 11.setName ("Zack"); 11.setStipend (10800.00); 11.writeOutput(); pause(); System.out.printf("%s's stipend is $94.2 Note: You do not need to submit your modified file package 105; import java.util.Scanner; A program to demonstrate inheritance using a simple hierarchy.
