        BufferedReader input = new BufferedReader(new InputStreamReader(System.in));
        System.out.println("Enter data");
        try {
            String data = input.readLine();
            System.out.println(data);
        }
        catch(Exception ex)
        {
            System.out.println(ex.getMessage());
        }

        Boolean b1 = Boolean.valueOf("false");
        System.out.println(b1);
