Yay for me! Yay for Java!

Well, I finally have a working J2ME environment. I was having some minor troubles making .jar/.jad files and compiling, etc. But I downloaded NetBeans (http://www.netbeans.org) and all is fine now. I've compiled some examples, run them in emulators, and even tested them with my phone.

So, all I need to do now is learn Java.

The syntax in java is the best I have ever seen out of any language. I think you will enjoy it.

I am currently looking for a java text editor, for a program that I have to compile with a script. By java text editor I mean a editor that highlights data types and such in different colors (like an IDE does).

Textpad works fairly well for that Pyro. I think it has all the features you want.

Thanks!!!!!!! Usually I just use BlueJ for an IDE, but for this program I can't.

I hate Java.

I understand it has its good points, and I'm well aware of some of its bad points, and I understand that hating a perfectly usable language is dumb...

But I can't help it. I hate Java.

Yep. I recently finished 2 java courses and my prof made us use Textpad. Good stuff!

I use netbeans. look around sun's website for Sun One 4, the predessorr to it, i find it to be much better unless you ARE actually making netbeans.

no compiling also. remmeber this is java.

oh and never yay for java, never yay. you'll never say yay for java once you learn it.

Java ain't too bad, till you find out it's limitations.

It was a shame that they taught me Java at Uni rather than C++. I still can't get my head around it yet, mainly due to the lack of reference material but i'll look at some books or something.

Still Java's pretty fast and Object Orientated so really decent programming is possible but it takes a fair amount of work.

i like java quite a lot, we only learned java at college, but it works OK for me, i can easily understand code and all

at the start of the year we got a course in C for microcontrollers, now that i just couldnt get

I use Ultraedit - it has syntax highlighting for about every lamguage out there, and if by some miracle its missing the one you need, you can add it yourself as a txt file of syntax you want highlighting, and what colours to highlight whatever commands you want in.

Java compiles into bytecode.

It is then interpreted though.
Advantages:
Java is multiplatform
Programs can be viewed through web browsers
Better syntax for object orientation IMO than C++

Disadvantages:
Slower than C++

You can compile to .jar, but I still think the program is interpreted.

Not true, has been disproved on many occasions.

I would go find the links to it but i've lost them.

maybe not relatively, but the java VM IS slower than C++ in both processor and memory usage. maybe the code ends up being slightly faster (i HIGHLY doubt that) but the overhead is much much greater.

another disadvantage is that even though its more easily portable, there are many legacy systems which do not have VMs for them.

I have a very specific use for Java. Hint: J2ME is Java 2 Mobile Edition.

Java does have its pros, but I just found it too high-level for my liking. I'd still rather work in C/C++ or asm...

Yes indeed, but I can't write C/C++ apps for my cell phone.

I was thinking of getting into J2ME...

But I don't have a cell phone.

Which I don't have. I have a Nokia 3120. Plus, looking at things, it seems that if I keep it to MIDP 1.0 and CLDC 1.0 I should be able to target the largest section of mobile phone users.
