Hi All,

Given the below snippet of code





Are the above two bw writer and bpw writer correct? Is it ok to wrap BufferedWriter with Printwriter? If yes, which one to choose among the two writers defined above?

Thanks

The first one (wrapping a BW around a PW) doesn't make much sense, for two reasons.

Firstly, the reason to use a BW is to avoid writing lots of small data items to a Writer that could be costly to access (like a File or a network connection). So you want it to sit right above that access, not someplace higher up in the I/O pipeline.

Secondly, wrapping a PW with a BW obscures the additional functionality that a PW provides, namely all the print and prinln methods. If you can't access those, there's no point in using a PW at all.
