      public int read​(byte[] buf, int off, int len) throws IOException
      Reads uncompressed data into an array of bytes. If len is not zero, the method will block until some input can be decompressed; otherwise, no bytes are read and 0 is returned.
      read in class InflaterInputStream
      buf - the buffer into which the data is read
      off - the start offset in the destination array b
      len - the maximum number of bytes read
      the actual number of bytes read, or -1 if the end of the compressed input stream is reached
      NullPointerException - If buf is null.
      IndexOutOfBoundsException - If off is negative, len is negative, or len is greater than buf.length - off
      ZipException - if the compressed input data is corrupt.
      IOException - if an I/O error has occurred.
