Hi,
I got exercise 2.3 to work by some advanced reading, Sang's topic #5 -
exception handling.
Here's the piece of code I want to share:
> public static void main(String[] args) {
> // TODO code application logic here
> try {
> FileInputStream propfile =
> new FileInputStream("myProperties.txt");
> Properties p = new Properties(System.getProperties());
> p.load(propfile);
> p.setProperty("myKey1", "dan");
> System.setProperties(p);
> System.getProperties().list(System.out);
>
> } catch (FileNotFoundException e) {
> System.out.println("error - file not found");
> } catch (SecurityException e) {
> System.out.println("error - security");
> } catch (IOException e) {
> System.out.println("error - IO ");
> }
>
> }
>
> }
