Post subject:  Request a Tutorial
Ok since there are three different individuals (as of today: Feb 05, 2004) that know java enough to write tutorials (whether its simple or advance) and there are a lot of individuals in the process of learning this language, I decided to create one thread in which people may suggest a tutorial. This way what the public wants is what the public gets (hopefully).

So go ahead guys, post:

I'm just coming to Java from turing so I read the hello world tutorial which was very good but it only did output not input. So a tutarial on input would be good and also a tutorial on if staments would also be nice.

I might just be blind and missed something if there is a tutorial alread on these I appologize.

How about a tutorial all about Abstract classes? For fun, in my spare time, I'm making a chemistry program that should be able to pass grade 11/12 Chemistry (balance equations, determine empirical formulas, predict products, model molecules, etc) and I'm thinking of structuring it as an abstract class "Element" and have each Element inherit it and give it their own twist (since many elements have lots of strange exceptions, like Boron being OK with a 6-electron octet, etc). But I'm afraid I don't know enough about Abstract classes to implement this model as efficiently as it could be. And besides, it's an important OOP concept that probably others would find very useful Smile

While I usually am the first to say that Java and C++ are radically different programming languages, when it comes to if statements, they work pretty much identically.

thats a webservice tutorial... not a java networking tutorial. there's a difference. webservice is more of a philosophy and stresses on os/implementation independent, interoperability.

its makes networking a hell a lot easier, with one drawback (well for xml-webservices anyways) it add a lot to the network overhead. i mean every call to a remote procedure sends an xml document describing the results which the client inteprets and converts to a usable form.

RPC can also be done using the Java RMI (Remote Method Invocation) package. It provides similar functionality as xml-rpc webservices, but it does not send an entire xml doc, instead binary packets. Thus it improves performance. The drawback here is that it does not stress on interoperability. It's a good choice but it will not teach you anything about real java networking.

For that you would definately require a tutorial of somesort in the java.net package. Wink

Can you please make a Tut for Buttons For Dummies Confused .. yea..... i know the swing class .. . but basically i want to add buttons to make a calculator..

this is basically what i want to learn how to do
code:

loop
// swing input "enter number 1"
create a window with all the operation buttons

display button with text "+"
if you press button "+" then
operation ="Add";
display button with "-"
//etc..

// swing input "number 2"
if (operation.equalsTo == "add")
result = n1 + n2;
else
yada yada

display result
exit if you push exit button
end loop


.. so if anyone were to make a buttons for dummies tut.. i would greatly apreciate it

thanks

That would require Java to be somehow magically "clean". You can write fugly code in Java. You can write fugly code in any language.

That would require reinventing quite a bit of the wheel, since HtmlUrlConnection, is quite a low level HTTP class.

I suggest you try: http://jakarta.apache.org/commons/httpclient

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

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

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.

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.

Post subject:  Re: Request a Tutorial
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.

I would like a java tutorial on JLists and JTables, how add data to them, remove data from them and return data from them to your program. Also how to know when the user has clicked on a diffrent item in the list or table. I've tried teaching it to myself but ListDataListener and other things are giving me compile errors saying that it can't find them, I have swing and awt.event imported too.

Interfaces in the OOP sense, or in the "I can click this on the screen" sense?

For the latter, I doubt you'll find it. Graphical User Interfaces are big and complex and have many possibilities. Tutorials on that subject will teach you to go from A to B and B to C, but they will assume that if you can do that, you know how to go from A to C.

What about a tutorial on how to make a basic game? I've already looked at the introduction to Java, which helped A LOT, but I'm still not really sure how all that could create a game.

I think I found something similar in the Turing section when I was programming in Turing, so I'd like to see one here just to get me started.
