This essay does not describe an existing computer program, just one that should exist. This essay is about a suggested student project in Java programming. This essay gives a rough overview of how it might work. I have no source, object, specifications, file layouts or anything else useful to implementing this project. Everything I have prepared to help you is right here.
This project outline is not like the artificial, tidy little problems you are spoon-fed in school, when all the facts you need are included, nothing extraneous is mentioned, the answer is fully specified, along with hints to nudge you toward a single expected canonical solution. This project is much more like the real world of messy problems where it is up to you to fully the define the end point, or a series of ever more difficult versions of this project and research the information yourself to solve them.
Everything I have to say to help you with this project is written below. I am not prepared to help you implement it; or give you any additional materials. I have too many other projects of my own.
Though I am a programmer by profession, I don’t do people’s homework for them. That just robs them of an education.
You have my full permission to implement this project in any way you please and to keep all the profits from your endeavour.
Please do not email me about this project without reading the disclaimer above.
This project is related to the Path and Classpath tool project and Which and What Project: path and classpath analysis projects in that they involve analysing the classpath.This project is easy in that it requires no design or user interface. It is an exercise in fiddling bits and using JDK (Java Development Kit) methods.
Let us say you have written code that will allow the user to add it own plugins, simply by implementing some interface. It would be nice to list all possible classes on the classpath that implement the interface (or extends a given class), so that you can add them to a JComboBox to let the user select which of all possible plug-in he wants to use.
How do you prepare the list?
Most of what you need for a classpath search is implemented in ZipLock. See the storeClass(String className) method and the openResource(,) method it calls.
