Ready to Program Java IDE and Unicode?

[Aziz]

Just not rtp, for the love of god

[FileFantasy]

Haha, yea, trying to get rid of RTP, and I think I'll suggest JCreator LE to the teacher rather than NetBeans, it looks more complicated although I think it has more features than JCreator LE.

Never tried Eclipse.

Why exactly do schools insist on using RTP? I myself have never used it, but I've heard many a horror story about it. Is it something to do with Holtsoft tightening their stranglehold on Ontario's Computer Science Curriculum?

[Aziz]

First off, because Holtsoft produces Turing. So they think they're getting a wonderful product. Holtsoft also provides many books that go along with RTP. Also, it's a "learning" program. And it costs money. I think a freeware program is "not good enough" for schools, they need something "professional".

[FileFantasy]

No idea. But this year's tech teacher agrees that we shouldn't use it, so it's all good.

I still don't know how to get CJK characters to display though, haha...

[Aziz]

That *was* the topic eh? Well, what did that google search result in? Anything useful?

[FileFantasy]

I did try to google it, but nothing gave me what I want, which is an explanation of why the code in my first post returns "?", and then an example of how it should be done properly (with source code).

Like, I want a "hello world" example, but in CJK characters.

i say rebel against ur school. hack into the server, and change it to normal java on every computer that wudn't b as hard as trying to get help on it lol.

[ericfourfour]

Well, I'd hate to break it to you gsquare567 but the Java is normal at school. It just uses an out of date compiler, and a questionable IDE.

[Aziz]

Did you look at the Internationalization tutorial? http://java.sun.com/docs/books/tutorial/i18n/index.html And I'm not exactly sure what CJK characters are.

[wtd]

If I had to guess, I'd say the acronym stands for Chinese, Japanese and Korean.

[FileFantasy]

Aziz,
I have, but it's so confusing that I have no idea which page to go to in order to find a simple "hello world" example of what I want, if there even is one.

---------------------------

wtd,

It indeed does.

Like, what I'm trying to do is display, for example, the unicode 4e00 on-screen, right?

That character should look like a dash ("-"), except a bit longer.

However, when I do System.out.print ("\u4e00"), a question mark ("?") is displayed instead. This go for any unicode that is in the 4E00-9FA5 range. (These are Unicode CJK Unified Ideographs)

The question is, what font are you using?

[FileFantasy]

Um, I don't specify. I just did what posted code on the first page, so I guess it's using default font, whatever that is.

[FileFantasy]

Ah, ok, I decided to look into the font issue, and I found out that if I use swing, and set font of a jtextfield to Simsun or PMingLiU, and then set text to "\u4e00", it displays it properly!

Issue solved, for now. Thanks everyone!

------------------

Ugh, now I have a new question...

Is it possible to make user input the hex, then display the unicode for that hex?

Ex. input: 4e00 output: (the chinese character for "1")

The trouble I have is when I type this in my source code:
Code:
output.setText ("\u"+input.getText());


It says that I have an "invalid unicode escape character".
