int read(byte[] b) throws IOException Note that most of the time you do NOT use InputStreams directly but use BufferedStreams, or similar. This is because InputStream reads from the source every time the read method is called. This can cause significant CPU usage in context switches into an...

IO may be blocking/non-blocking and synchronous/asynchronous. POSIX API provides synchronous blocking API (e.g. classic read, write, send, recv calls), synchronous non-blocking API (same functions, file descriptors opened with O_NONBLOCK flag and IO-multiplexing calls) and asynchonous API (functions...
