Japanese in Java

Link | by ChaosDevil on 2008-04-09 16:52:15

Okay, so I'm using Jbuilder and would like to display Japanese Characters in the console. The following is the only way I could manage to get it to display albeit it only displays in a popup:
-------------
---------------------
import java.util.*;
import java.io.*;
import javax.swing.*;

public class japanese_test_class {
public static void main(String[] args)
throws IOException, FileNotFoundException {
PrintWriter output = new PrintWriter("temp.txt", "Cp933");
System.out.println("ã²ã‚‰ãŒãªã€€ã®ã€€ã‘ã‚“ã•ã€€ã§ã™ã€‚\u3041"); //Testing hiragana and unicode... both failed.
String test = "ã²ã‚‰ãŒãªã€€ã®ã€€ã‘ã‚“ã• \u3041";// Testing if String will contain it... Failed
System.out.println(test);
//only the following popup displays the text...
output.println( "\u3041 ãŠã„ï¼ã€€ãƒ¬ã‚¤ã€€ã§ã™ã€‚ ã‚ˆã‚ã—ãã€€ãŠããŒã„ã—ã¾ã™ã€‚Hey Thereï¼ Rey Here. Pleasure to make your acquaintance." );
output.println( "Hey Thereï¼ Reyã€€Here. Pleasure to make your acquaintance." );
output.close();

Scanner input = new Scanner(new File("temp.txt"), "Cp933");
JOptionPane.showMessageDialog(null, input.nextLine());
}
}
-----------------------
--------------

I would like to have the Japanese display using system.out.println("xxxx") and not have it as a pop up.
(This is my first Java Class but I'm hoping to have my final project be a program that aids students in learning Japanese Characters. I'm using OS X 10.5.2)

If you have suggestions for a different IDE that's Leopard Compatible please do suggest.

Thank you VERY VERY MUCH in advance!! ^_^

Try this:

System.setOut(new PrintStream(System.out, true, "UTF8"));

Hmmm I've used your tip and it did infact alter the text but it still only displays gibberish (Before it was all "?" characters, now they're all random symbols but not actual Japanese).

I'm using a Japanese compatible font (Hiragino Mincho ProN)
And have tried all the encodings I have available.

I can see that what you gave me is a step in the right direction... but It's not quite what I'm looking for. Perhaps you have a slightly different setup from me and this produced the desired result. Would you mind explaining what setup you use, (if you actually have used Japanese text in java before that is) :-)

Thanks again

It may be that your Java source file its self is not UTF8 encoded.
You might think about having the Japanese strings loaded from a data file on startup.

Well I was able to make the Japanese display Properly (All I did was make a new user account on my computer with Japanese as the default language) That seemed to be the easiest way to accomplish it. Anyway, Now that I have that out of the way I have a more basic question (remember this is my first programing class)

How can I change the size of the font.

For Example:

æœˆ (200 pt. font size)
[User input] (60 pt. font size)

Would I need to import anything in particular or is java.io enough?

To change font size, you will need to use graphical display instead of java.io.
