Java编码转换

于Java当中，编码格式的转换一般较为麻烦，就我目前的经验来说，需要用到转码的环境主要是IO（无论是网络IO还是文件IO）。转换方式主要有以下几种

 

方式一：String层面 

　　

 String message = "中国";
 System.out.println(new String(message.getBytes("GBK"), "GBK"));

方式二：IO层面

public class Test {
    public static void main(String[] args) throws IOException {
        BufferedWriter writer = null;
        BufferedReader reader = null;
        String encoding = "GBK";
        String remoteFileName = "";
        // 编码
        writer = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(
                remoteFileName), encoding));
        //解码
        reader = new BufferedReader(new InputStreamReader(new FileInputStream(
                remoteFileName), encoding));
        writer.close();
        reader.close();
    }
}
