Is this better?
private void javac(Path source, Path destination) throws IOException {
Stream<String> prefix = Stream.of("-d", destination.toString());
Stream<String> suffix = Files.isDirectory(source)
? Files.walk(source)
.map(Path::toString)
.filter(s -> s.endsWith(".java"))
: Stream.of(source.toString());
String[] args = Stream.concat(prefix, suffix).toArray(String[]::new);
JAVAC_TOOL.run(System.out, System.err, args);
}
