HOMEWORK 4

CS332

1) Study Chapter 6 of the textbook (ALL).

2) Finish up Chapter 13 ( Note: ALL the material of this chapter will be covered in the midterm test )

3) Write an interface representing a Developer: it will include public methods returning whether or not he/she is currently employed, his/her name, if he/she is a Java or VB programmer, number of years of experience, and the public method

void writeCode() ; then write 2 implementations of Developer, VBDeveloper and JavaDeveloper.

The two implementation will differ only in the writeCode() method: when writeCode() is called on a VBDeveloper, it says:

”VB is pretty easy”. When it is called on a JavaDeveloper, it says: “hey, java is not so bad!”.

Finally, write a Factory class for Developer, with a method Developer createDeveloper(boolean switch):

if switch is true, the developer is actually a VBDeveloper, else he/she is a JavaDeveloper.

Write a test driver for this HW.
