    已过时。 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.
    
    参数:
    
    out - the stream to write the data and fields to
    
    抛出:
    
    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
