Java Class Overview

Disclaimer

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.

Overview of Java Classes Sorted By Class Name
java.lang	Object	java.util	Calendar	abstract	Used for doing date/time calculations. Mother of classes that handle Christian, Islamic, Buddhist etc calendars.	java.util.GregorianCalendar	java.util.Date, java.util.DateFormat, java.util.TimeZone
		java.lang	Comparable	interface	Defines the natural ordering of the objects in a class.
java.lang	Object	java.util	Date	class	Object wrapper around a long timestamp, without an embedded TimeZone. Mostly deprecated.	java.sql.Date, java.sql.TimeStamp, java.sql.Time	java.util.GregorianCalendar, java.util.TimeZone
java.util	Calendar	java.util	GregorianCalendar	class	Used for doing date/time calculations. Contains long timestamp and a TimeZone.		java.util.Date, java.util.DateFormat, java.util.TimeZone

Prepare versions of the table sorted by parent package, parent, package and class. Set up HTML (Hypertext Markup Language) to flip between views similar to the HTML colour charts.

Repackage the data as an Applet so you don’t need to download the data over just to see a different sort. The raw data comes over in serialized object form, compressed inside a jar for fast download.

Allow the user to ask questions of the form:

What classes implement this interface directly/indirectly?
What classes implement this abstract class directly/indirectly?
What classes extend this class, directly/indirectly?
What is the ancestor chain of this class?
What interfaces does this class implement?
Show me the table, filtered, so that only the entries containing the string time are displayed.

Provide hooks into the standard JDK (Java Development Kit) API (Application Programming Interface) either on Oracle’s site, or locally if available to get detail about any class and its methods. When you click a class name it takes you to the corresponding spot in the JDK Javadoc.

Use a DocLet to automatically extract all the inheritance structure from the Javadoc. This is the only way to ensure it is accurate and up to date.
