public class IOZhuanHuan {

    public static void main(String[] args) throws IOException {
        // TODO 自动生成的方法存根
        String src="你好啊！";
        InputStream is=new ByteArrayInputStream(src.getBytes("utf-8"));//字符流转字节流

        BufferedReader in=new BufferedReader(new InputStreamReader(is,"utf-8"));//字节转字符
        System.out.println(in.readLine());
    }
