[netcdf-java] NetcdfFileWriteable setName() is deprecated, but i don't know what else to use

Hi,
I have a problem to achieve my goal. My goal is: opening an existing netcd file, make some modification to it, then output to a different netcdf file. My java code is like the following:
final NetcdfFileWriteable writableFile = NetcdfFileWriteable.openExisting(inputNetcdfFileName); //open an existing input netcdf file. writableFile is not blank, it has everything defined in the input netcdf file. 

       writableFile.setRedefineMode(true);

      //did some modification, like changing variable values, etc
writableFile.setName(outputFileName); //i want to write out to a different netcdf file, i don't want to overwrite the original input netcdf file 

The code above works fine for me. However, setName() is *Deprecated.
*


     setName

public void *setName*(java.lang.String filename)

   *Deprecated.* /use NetcdfFileWriteable.createNew(String filename);/

   Set the filename of a new file to be created: call before calling
   create().

   *Parameters:*
       |filename| - name of new file to create.
/NetcdfFileWriteable.createNew(String filename) /is different thing. It returns a blank netcdf file object.
final NetcdfFileWriteable writableFile = NetcdfFileWriteable.createNew(fileName); //now, writableFile is blank
How can I avoid using deprecated setName() to achieve my goal? Thank you very much.
