Neopets Programming with Java

[Sean]

This is just a quick write up with some .java files to help you get started. Joe requested this from me a while ago and I've been slacking on putting it up.

First things first, a few files that may be beneficial to you:

Connection.java

This is the 'wrapper' or what you would use to connect to neopets and interact.
It's simple to use. Once you create a new instance its just neo.get("") and neo.post("", new String[][] { {}, {} });
If you need to set a referer, you can do that manually. Otherwise, the referer is set to the last page. There are a few modifications in this that I added such as proxy support, support for the potential botcheck, etc.

Apart from this, what joe really wanted was the gui creator for eclipse that I use.

Currently, I am using google's WindowBuilder Pro. It's a simple eclipse add-on that allows for quick gui creation. There are some bugs that i've found with it but nothing major and it should work for whatever you want to make.

That's all I'm going to post for now but if you have any other questions then feel free to ask.

I highly recommend this post to anyone wanting to learn Java programming or programming in general.

Java is a cross-platform programming language meaning your programs can be ran on any operating system.

Ahh that's good so if I go back to my windows XP computer someday I can use them on there, awesome :*

[deathwish42]

wow thats amazing nice job im currently trying to learn java on codecademy im stuck on it though so ya nice topic i will come back to this once i learn how to do some major coding

[davebold370]

Coolness. It's a little more advance than what I know of java right now. What are the portals you use to access different things throughout neopets and how would i find those portals myself so i don't have to ask over and over again. lol Thank you so much. I love learning new things about programing and more involved i become with internet programing the better.

[BEDDOEDv]

im trying to learn about java, i find its slow though a times

[npm]

I'm studying java at school and this will really help me. I hope someday I can do a simple program for neopets by myself without asking anything and this is a really good begining for me (you know trying to learn about all the functions used on this and that :rolleyes:). So thank you :)

[Jesusinn]

I just learn java in the school too.
but I noob compared with him u.u
thanks so much for the tutorial :3

WB is a bit buggy, yes. In the sense that you drag and drop a window/widget/whatever (I forget the technical term WBPro uses) and it auto-places the code for you in your existing program in a place that isn't exactly organized (or as organized as you'd want it to be)... which means you may have to manually put it somewhere else, every single time you drop a window/widget onto the screen.

There is always straight coding via AWT and SWING, which I prefer; but am recently taking to JavaFX as a means to create a more attractive GUI for potential users... and JavaFX is, to me, a bit ghetto in the sense that its still new- and yes- there are several known bugs.

Couple on top of all this, any time plug-ins are being installed with eclipse; you may have some kind of unexpected or unwarranted behaviour (such as the well-known "R" or Resource bug commonplace with Google's ADT Plug-In for Android Developers)

I feel that Java is kinda' wanting when it comes to GUI development ( lacking the sheer simplicity of VB ); though every language/platform seems to have its own advantages over others, and simply familiarizing yourself with every language/platform's nuances will indeed make the process a lot more comfortable, as you get used to experiencing these same nuances over time and can work around or fix them via personal experience, effortlessly. But that all comes with familiarity and practice.

[eggloo]

is java the best program for np bots?

[hamstergleufje]

LOL wow looks so hard

[ozfe]

This is amazing! Thanks so much!
