Dear all

I am now reading the book of HF Servlet & JSP 2nd and found the following code:



And the BeerExpert class:



Well, the question is that, BeerSelect.java cannot be compiled with the following well-know warning:



Actually I know that, when I use the @SuppressWarnings("unchecked") statement above the "List<String> result = be.getBrands(c);", the code can be compiled nicely. However, I don't want to avoid that everytime when I meet this error. But the question is : how can I change to have it compiled?

Can anyone please help me to solve this problem?

Thank you very much in advance for all your help.

Your getBrands method in BeerExpert class may return a List of Strings. That will solve the problem (actually that's a warning not a compiler error), though you may be able to run the code without it
