乱码的产生

import java.io.File;
import java.io.FileOutputStream;
import java.io.OutputStream;

public class CharSetDemo02 {
    public static void main(String[] args) throws Exception {
        File file = new File("f:" + File.separator + "loser.txt");
        File file2 = new File("f:" + File.separator + "winner.txt");
        OutputStream out = new FileOutputStream(file);
        OutputStream out2 = new FileOutputStream(file2);
        byte b[] = "中国、こんいちは！".getBytes("ISO8859-1");
        byte b2[] = "日本、コンバは！！！".getBytes("MS932");
        out.write(b);
        out2.write(b2);
        out2.close();
        out.close();
    }
}

乱码产生的原因就有一个，即输出内容的编码（例如：程序指定）与接收内容的编码（如本机环境默认）不一致。
