                  throws java.io.IOException
```
    Writes the configuration data from the Dictionary to the given OutputStream.
    This method writes at the current location in the stream and does not close the outputstream.
    
    Parameters:
    out - The OutputStream to write the configurtion data to.
    properties - The Dictionary to write.
    
    Throws:
    
    java.io.IOException - If an error occurrs writing to the output stream.
  - read
```
public static java.util.Dictionary read(java.io.InputStream ins)
                                 throws java.io.IOException
```
    Reads configuration data from the given InputStream and returns a new Dictionary object containing the data.
    This method reads from the current location in the stream upto the end of the stream but does not close the stream at the end.
    
    Parameters:
    ins - The InputStream from which to read the configuration data.
    
    Returns:
    A Dictionary object containing the configuration data. This object may be empty if the stream contains no configuration data.
    
    Throws:
    
    java.io.IOException - If an error occurrs reading from the stream. This exception is also thrown if a syntax error is encountered.
