Advances this scanner past the current line and returns the input that was skipped.

Usage

From source file:ThreadPoolTest.java

public static void main(String[] args) throws Exception {
    Scanner in = new Scanner(System.in);
    System.out.print("Enter base directory (e.g. /usr/local/jdk5.0/src): ");
    String directory = in.nextLine();
    System.out.print("Enter keyword (e.g. volatile): ");
    String keyword = in.nextLine();

    ExecutorService pool = Executors.newCachedThreadPool();

    MatchCounter counter = new MatchCounter(new File(directory), keyword, pool);
    Future<Integer> result = pool.submit(counter);

    try {/* w  w w . j  av a  2  s. c  o m*/
        System.out.println(result.get() + " matching files.");
    } catch (ExecutionException e) {
        e.printStackTrace();
    } catch (InterruptedException e) {
    }
    pool.shutdown();
