Here, I bring you a great extension for your programs. With it, you can edit .properties files almost like in Java. Here, I´ll show you how to use it: Property P = new Property(); As you can see, we create and set it so simply. P.setFileRoute(ROUTE); With this method, you add the path/route of the file (without this, you can´t do anything with the property). P.setProperty(VALUE, KEY); With this method you add a property value/name and its value to the file, or if it doesn´t exist, it´ll create a new one with this elements. P.getPropertyValue(LINE); P.getPropertyKey(LINE); With this methods, you can get the value or the key of a line chosen from the file. IMPORTANT - Line counting doesn´t go like this: 1,2,3,4... It goes like this - 0,1,2,3,4... (In programming it starts from 0). I hope you like this extension / class!
