bufferedreader in java

is this the correct use of bufferedReader if I'm only using it once?

String s = BufferedReader(new InputStreamReader(System.in)).newLine();

Almost. You need to call close() on the BufferedReader after you're done with it, which means you need to keep a reference to it.

try {
  BufferedReader buffa = new BufferedReader(new InputStreamReader(System.in));
  String s = buffa.readLine();
  buffa.close();
} catch (IOException e) {
  e.printStackTrace();
}
