thnx


Learn about three things, and you won't need a tutorial on this subject. Smile

  • Interfaces
  • Anonymous Inner Classes
  • How to use the API refs at java.sun.com

i just read wat u wrote about interfaces and dont see a connection yet. i am making a simple maze game and just need to know how to translate the arrow keys to the movements in the game. If there is a simpler way plz lemme kno. i will still continue to look at the other two things u mentioned previously.

Java has anonymous inner classes (among other reasons) because it lacks a way to anonymously defines first class chunks of executable code any other way.

Anonymous inner classes are just subclasses of Object that implement an interface. By defining an anonymous inner class that implements an ActionListener interface, we can essentially provide a callback function, to be called when a given "action" occurs.

Here's a different one . . . a tutorial on making javadocs of your programs, and its uses.

okay i know this isn't java specific but its the language that i'm working with right now so maybe a tutorial on recursion, graphs and trees b/c my comp sci teacher has not covered it. as well a tutorial that goes more indepth with swing. creating scrollers, textfields. Jlabels, Jframes, buttons, the works. but esspecially one for the top one would be very helpful.

Is there a good tutorial on recursion I can use?

Recursion is so devastatingly simple if you know how to write and call methods that I am reasonably certain no tutorial is required beyond what has been provided. Smile

Fair enough I guess. I just looked at your recursion example and usage in your intro to Java and its understandable. I get the basis of recursion and all but if possible could more applications be suggested? Maybe an example program or two where recursion is used in a more complicated matter? But other than that thanks wtd I get the basic idea.

I'm not sure if I still have it, but I'll check and see if I still have my notes and example code from a class I had a semester or two ago on it. I kind of doubt it, to be honest, but I'll dig around a bit.

About recursion - the example they used in my classes a lot was that of a function that generated the Fibonacci sequence. In actual use, cases where it wasn't obvious that we were doing it just for the sake of doing recursion, the only place I ever remember doing recursive code is when dealing with trees, so if you're familiar with them and want to do more "real" examples, that'd be a good place to start.
