The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

C++ templates vs. Java generics

Asked by DJ_AM_Juicebox in C++ Programming Language

Tags: java, generics, templates, vs

Hi,

Can anyone compare C++ templates to Java generics? I just wrote a program using java generics and they seemed a little easier to use than templates (of course I did some really basic stuff).  For instance in java I defined a node wrapper class like:

    public class CNode<T> {
   
        // The generic data we're wrapping around.
        T m_data;
   
        // Pointer to the next node element, if any.
        CNode<T> next;
   
        // Pointer to the previous node element, if any.
        CNode<T> prev;
   
        /** Creates a new instance of CNode */
        public CNode(T t)
        {
            m_data = t;
            next   = null;
            prev   = null;
        }
    }

which is pretty simple, my C++ version I had to figure out that anything that touched my template had to be moved into the header file (if I did that right) and was a little annoying because it broke my usual style of always having the function bodies in corresponding cpp files.

Anyone care to comment on their experience(s) between the two?

Thanks
