Re: Best method of reading/writing files 12 Years Ago by JamesCherrill FileReader is just a subclass of InputStreamReader, with defaults for the settings you have to handle explicitly in InputStreamReader - so unless you want to do anything special it's just the same this but a bit more convenient. Check out the API doc for FileReader for full details.
