Dear,
I have a method called (getContentObject) which returns me an Object[]. I have a piece of code like this:

result = (Object[]) reply.getContentObject();
double price = Double.parseDouble((String)result[2]);

actually in the last line I've tried to convert object to double but I cant. can you tell me how can I make it ?

Thanks,
Sahar.
