BufferedWriter class final
Wraps a writer and buffers its output.
It can be excessively inefficient to work directly with something that implements Writer. For example, every call to write on a network socket results in a sytem call. A BufferedWriter keeps an in-memory buffer of data and writes to to an underlying writer in larger batches.
BufferedWriter can improve the speed of programs that make small and repeated write calls to the same file or network socket, but will have no effect on programs that write large chunks of data at once or just writing a few times, or to writing to an in-memory buffer.
