You can't cast null objects. Using the same API call, you can re-write
the method as
Public String getProperty(String prop) {
Object val = config.getProperty(prop);
if( val == null ) {
return null;
} else {
return (String)val;
}
}
However, that's a lesson in Java. More practically, why not simply
call getString(prop); - that returns a String directly.
