javaの多言語対応

An identifier is an unlimited-length sequence of Unicode letters and digits, the first of which must be a letter. Letters and digits may be drawn from the entire Unicode character set, which supports most writing scripts in use in the world today. This allows programmers to use identifiers in their programs that are written in their native languages.

とThe Java(TM) (TM)Virtual Machine Specificationに書いてあったので、試してみたら本当に色んな言語の識別子をコード内で使えるんですね。もちろんコードの文字コードはUTF-8とかにしておく必要がありますが。

下に例をあげます。このコードは本当に動きます。

import java.lang.*;

public class test {

	static class 크라스 {

		public 크라스() { }

		private String collège = "日本語한국어";

	}

	public static void 関数(크라스 くらす) {

		System.out.println(くらす.collège);

	}

	public static void main(String arg[]) {

		크라스 ほげ = new 크라스();

		test.関数(ほげ);

	}

}
