Is there any reason to prefer a CharBuffer to a char[] in the following:
CharBuffer buf = CharBuffer.allocate(DEFAULT_BUFFER_SIZE);
while( in.read(buf) >= 0 ) {
out.append( buf.flip() );
buf.clear();
}
vs.
char[] buf = new char[DEFAULT_BUFFER_SIZE];
int n;
while( (n = in.read(buf)) >= 0 ) {
out.write( buf, 0, n );
}
(where in is a Reader and out in a Writer)?
Answer
No, there's really no reason to prefer a CharBuffer in this case.
In general, though, CharBuffer (and ByteBuffer) can really simplify APIs and encourage correct processing. If you were designing a public API, it's definitely worth considering a buffer-oriented API.
