It may throw a 'checked' exception so you must provide a way to deal with
that possibility.

String ns = null;
try {
ns = stdin.readLine();
}
catch(java.io.IOException ex) {
ex.printStackTrace();
}

note ns is declared outside of the try/catch block so that the reference
remains in scope so you can use it later.
