YES! I second what BuddyBob said!

I started Java when I was 16 as well (I'm 18 now, turning 19 in June) and I'm very glad to see another young blood on these forums.  You will find nothing but exceptional help on these forums, do not worry about how big or little the problem is, you will always find help here.

Peace,
Draco

Thanks for the warm welcome!

I'm very curious how the new version of JCreator will work...
There isn't much info about it. Anyone has more info about it?

Just a little question: Is Xinox one person? If so, are there other people helping to develop JCreator who're also active on these forums?

Thanks again. Now I know a forum for where to ask those Java n00b questions :p

[E-E-R]

xinox is the only active forum user that actually works for xinox, AFAIK. However, Xinox Software is not a one man company, as can be seen on the contact page (http://www.jcreator.com/xinox.htm) there are at least two people working there.

I would estimate there may be around 5 to 10 people working for Xinox (However, it's just a guess).

Several years ago I wrote a GUI that allowed the user to input (textually or graphically) geographic coordinates and then display those coordinates on a flat representation of the earth.  The reason this was so hard is that I had to research earth curvature (ellipses, etc) and take that into account when plotting the points.  The math for that was absolutely insane, and when I go back to look at it now, I have no clue how I figured it out.

In all, though, the hardest coding job is other people's code.  Nothing is worse than maintaining really bad code that you have no power to replace.

Sounds like some pretty intense math eh? Was it something to do with Mercator projections?

Yup, ure right! The hardest job is to figure out other's code and debug it. Once you are assigned to debug others' code, it is then that you know the value of coding conventions and proper documentation.

Making two JTree's in one pane with:
* copy/move and synchronize from one root to another
* locate objects on JTree
* select/deselect
* manage user Object Pointers
* maintain sort order during copy/move operations
* allow renaming of the roots (folder containers) disallow editing of child items
* making the tree objects universal - to handle/manage ANY user object I throw at it.

I still can't get:
* Drag and drop across trees
* DND within a single tree

the trouble with tribbles - or JTree's as it were....  Anyone got any good JTree DND code to share?

Cheers,
Dano

The hardest program I've ever done was a project for my intro to java class. We were assigned to write a simple GUI application that displays a graph of the sine curve which could be manipulated with sliders. Now that sounds easy, and it was. I knew it was coming and had all the requirments met (I spent part of a Saturday doing that) before it was even officially assigned. The real difficulty came when I decided to go beyond the project and add more features to it.

I started off by having it graph all six trig functions. I then added features similar to that of a TI graphing calculator (really all but TI's are what my school uses) such as window ranges, tracing of the function, verticle and horizontal axes, lines marking off the period of the function, and a zoom box. I set up the tracing and zoom box with a nice mouse only interface. Just click and drag the left mouse button to zoom in, and right click to zoom back out. Yeah it stacked the zooms. Tracing occured when the mouse was in the JPanel responsible for drawing everything. The hard parts to doing all this were:

a) How to scale the function itself to draw correctly.
b) How to best implement window ranging and implement the axes and period marks correctly.
c) Fixing rendering glitches.

I got it all working alright. Then over summer I went back to the trig project and realized how bad all the code was. There really wasn't much of an object oriented design, which I fixed and the math involved with variable window ranges was embarassing. Fortunately the only other person besides me to have ever seen it was my teacher    But I had a lot of fun fixing all that stuff. Then this past February I started adding support for drawing custom equations, I got as far as a simple parabolic equation parser when an annual competition came up much earlier than expected and I haven't been back to fully implement the feature.

Time for hardest thing #2: Getting the 360 controller to work in Java.

Not that the process is at all difficult, but I have absolutely no c++ experience, which is what made it difficult. So I was fighting with Dev-cpp, it gave me some crap makefile bs so I switched to Visual Studio 2005. Once I figured out I needed a platform SDK and got some include files in the right spot all I had left to do was fix some minor syntax errors. Now, thanks to the JNI, I have the ability to control my apps with a 360 controller  

It's not really all that complicated, either. Which is good. Now that I have some experience, improving my code that handles the input should be a breeze.

Currently working on it.  I call it Degree Designer.  It's a complete web based Ed Plan collaboration suite for colleges.  It has to integrate with multiple legacy systems, have a dynamic work flow(because not every college approves Ed Plans the same way) and work fast.  I have been working on it for over 2 years now, and have even built a company around it.  It looks like we might have our 1.0 release by October of this year.  We are even getting colleges excited about the release and have some beta clients lined up.  I just released a spin off of the Degree Designer called FastSchedule.net, which takes our schedule optimization functions and lets colleges sign up and provide our search engine for their catalogs for free.
The entire way I have been using JCreator (since 2.5).  I wold guess at this point there over 90,000 lines of code in 6 languages (Java, JSP, Javascript, XML, CSS, HTML).  I look forward to many more years of using JCreator.  I have tried Eclipse, NetBeans, IDEA and StudioCreator, anything matches the clean, rapid, efficient environment of JCreator.  I just wish they would support 2 monitors better :P

Just curious to see what people have done out there in conerns to difficult projects.  

Just finished a parser and toolkit for XML Schema Definition (XSD) and DTD files.
Had to be able to reverse-engineer an XML document (with proper types and valid default values) from any schema root as well as be able to put the entire schema into a code model that humans can actually understand. (if you have seen any api's for XML schemas you know that they are difficult for advanced programmers)
Also had to be able to validate XML documents, provide REAL error messages, and validate the schema files themselves.

Hardest thing I have done in 25 years of programming. It was done in Java with jCreator.

I'm newer to programming so i would say an astriods mock.

I haven't run into any very hard programs, but I will in a year or two when I try and make a Blokus applet with a lot of features.

just a question,  can i pm u in dutch coz i got a problem with a practicum in java, (and i wont translate the whole thing to english)

[E-E-R]

Sorry, but no. I never answer questions via PM, if you have trouble translating, use Babelfish. (http://babelfish.altavista.com).

[javaboy0606]

I haven't done much in java and don't really have a hardest program I've ever written, but I am 15 and trying hard.

[Comady-cool]

16!!?? Cool dude! Very honored to see a young mind on this forum!

We've all climbed similar ladders in our programming career and we to were *Proud* of our creations!!!

All the best to ur programming career and looking forward to see ur participation on the forums!

Good thing he's not as young as me see(Why cant I put...........).

Java is very complicated to me.

[Comady-cool]

I agree to

[Kraicheck]

Stop doing that!

Resurrecting a thread with "I agree" is just asking to be banned.
If this board wasn't so lightly moderated (no offense to Xinox   ) you and several others would have been warned and probably banned already.

And if you respond to this with something along the lines of  "sorry but I'm young and ignorant" I'm going to hunt you down   .

[sameer]

Sent :)

the code is butt-ugly at some parts, but it works as intended.
It's just that the intention was to serve a page and *not* crash the server doing it, keep that in mind while you are reading the code ;)

pls send it to me as well

A current project I am doing for my Web-Based Java class. We are making Battleship. First version was console, second is graphical, and who knows from there. I would say the hardest part of it has been the AI of it. Especially when you get to multiple ships next to each other. It needs to be simple but smart at the same time and I'm no AI programmer. :D
