Stack Overflow Questions

1. Interface naming for adjectives

OK, so it's easy to name an interface (or class for that matter) if you can easily think of a noun: User, Window, Database, Stream, etc. What about an adjective or adjective concept? e.g. something that has a timestamp (HasTimestamp, Timestamped, Timestampable...?) or something that is tracked or watched (Trackable, IsTracked, Watchable, IsWatched...?)

2. Flushing input stream: java

Is there a way to flush the input stream in Java, perhaps prior to closing it? In relation to iteratively invoking the statements below, while reading several files on disk InputStream fileStream = item.openStream(); fileStream.close;
