In my opinion, it is usually not the first step to invoke/use C++ and Java classes for people in learning Ruby. If the question is just whether it is possible, I think the answer is definitely yes. If you really want to use some existing library of C++ or Java classes from Ruby, probably it is a good idea to check first whether some people have already done the work so that you can just include the extension and you don't need to know the underlying details. However, if you want to invoke your own C++ and Java classes from Ruby, it is in general not a trivial matter. Some pointers are: - If you want to see how to call C code from Ruby, you can scan the "Extending Ruby" Chapter of the "Programming Ruby" book. - If you want to use C++ classes from Ruby, you can scan the SWIG web site. - If you want to use Java classes from Ruby, you can scan the JRuby web site.
