- write
  
  @Deprecated public abstract void write(ObjectOutput out) throws IOException
  
  Deprecated.
  This method does not write the values contained by this PutField object in a proper format, and may result in corruption of the serialization stream. The correct way to write PutField data is by calling the ObjectOutputStream.writeFields() method.
  
  Write the data and fields to the specified ObjectOutput stream, which must be the same stream that produced this PutField object.
  
  Parameters:
  
  out - the stream to write the data and fields to
  
  Throws:
  
  IOException - if I/O errors occur while writing to the underlying stream
  
  IllegalArgumentException - if the specified stream is not the same stream that produced this PutField object
