使用Java中的DeflaterOutputStream和InflaterInputStream压缩和解压缩String

我需要在文件上保存一个字符串,我正在使用DeflaterOutputStream进行压缩.当我尝试解压缩时,我无法获得原始字符串.我得到一个未清除的符号.她是我的代码:

    public static void decompress() throws Exception {
    InputStream in=new FileInputStream("E:/codes.txt"); 
    InflaterInputStream ini = new InflaterInputStream(in);
    ByteArrayOutputStream bout =new ByteArrayOutputStream(512);
    int b;
    while ((b = in.read()) != -1) {
          bout.write(b);
    }
    ini.close();
    bout.close();
    String s=new String(bout.toByteArray());
    System.out.print(s);
}

public static void compressData(byte[] data) throws Exception {
    OutputStream out=new FileOutputStream("E:/test.txt");
    Deflater d = new Deflater();
    DeflaterOutputStream dout = new DeflaterOutputStream(out, d);
    dout.write(data);
    dout.close();
}
public static void main(String[] args) throws Exception {
    compressData("My name is Motasem".getBytes());
    decompress();

}

我不知道问题究竟在哪里.我虽然是将字节数组转换为String但我尝试了它并且它正在工作.你可以访问这个网站http://www.mkyong.com/java/how-do-convert-byte-array-to-string-in-java/
