Lab-02

Today's Activities

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 ($9,144). 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 InheritanceDemo.

Lecturer l1 = new Lecturer("Zachary"); Lecturer l1 = new Lecturer("Wilhelmina", 11017.00); l1.writeOutput(); l2.writeOutput(); pause(); l1.setName("Zack"); l1.setStipend(10800.00); l1.writeOutput(); pause(); System.out.printf("%s's stipend is $$4.2f.\n", g2.getName(), g2.getStipend());

• Lecturer claims to be a subclass of Person
• ... has the required extra field(s)
• ... does not have any field(s) it shouldn't
• ... has the two-argument constructor
• ... ... that sets the name and stipend correctly
• ... has the one-argument constructor
• ... ... that sets the name and stipend correctly
• ... constructors show correct use of this(...) and super(...)
• ... has all the getters and setters it should
• ... but none it shouldn't
• ... has a writeOutput method that does what it should
• All code conforms to the style guidelines for the course
