I got this error when writing a method. Here's the code... public int getPrice(){ return price; } Can anyone tell me what this means?

Here's the code... public int getPrice(){ return price; } Can anyone tell me what this means? Are you sure price is declared to be an int? If it is declared as a long, returning it as an int will let you lose precision if the value is larger than Integer.MAX_VALUE (2^32-1). The compiler will warn you about cases like this. You can get around it by explicitly casting the long to an int like this: public int getPrice(){ return (int)price; } -- Kind regards, Christophe Vanfleteren Back to top Ryan Stewart Guest Posted: Thu May 20, 2004 11:49 am    Post subject: Re: Possible Loss Of Precision??

It means that price is a long, float, or double, and you're trying to squeeze it into an int. Doing so could result in a loss of precision, so the compiler wants you to explicitly cast it so it knows you know what you're doing: public int getPrice() { return (int) price; } In the future, please try to provide a complete, compileable example that demonstrates your problem. You'll generally get more specific answers if you do so.

I thought we only had to contend with two self-publicists in the group: Roedy and Andrew. Now it seems that Andrew has obtained a minion. I look forward to seeing Roedy rallying his forces in the counter attack. John Back to top Shashank Guest Posted: Thu May 20, 2004 1:01 pm    Post subject: Re: Possible Loss Of Precision??

Just thought I'd say that your post itself contains a certain lack of precision - i.e. post all the code if possible, and the exact error message.... it will help others to answer you in the future. alex Back to top Alex Hunsley Guest Posted: Thu May 20, 2004 1:08 pm    Post subject: Re: Possible Loss Of Precision??

No. Quote: Would you sooner I wrote ones off the top of my head each time rather than polishing the same old answer? No. Quote: Would you sooner I kept the answers to myself? No. I'd sooner you were prepared to take yourself a tiny bit less seriously. You help all the newbs out very patiently, and I suppose that hosting pages of solutions is a useful tool in doing that. It just seems quite funny (to me) to see you, Andrew and his minion posting links to your own sites (as if seeking publicity). I am fully aware of the good it does, but it doesn't mean I can't wind you up about it. Quote: I think you have things rigged so I would never gain your approval no matter what my behaviour. Please don't get too paranoid. You already have my approval (see comments above). Quote: Have you ever tried clicking the links I provide to see if they are ads or indeed answers to the question? I have indeed. You must have put a few man-years into that site of yours. Anyway, what i'm interested in is how are you going to react to the advent of The Minion? Andrew has thrown down the gauntlet and nailed his colours to the mast with this swell in numbers. I can almost sense the bandwidth switching to http://www.physci.org/codes/sscce.jsp rather than http://mindprod.com/jgloss/errormessages.html .
