Open and run the project tech-support-complete. You run it by creating an object of class Support System and calling its start method. Enter some problems you might be having with your software, to try out the system. See how it behaves. Type "bye" when you are done. You do not need to examine the source code at this stage. This project is the complete solution that we will have developed by the end of this chapter. The purpose of this exercise is only to give you an idea of what we plan to achieve.
