Yes. Use JNI to call C / C++.
You can but I would not have any clue why you would want to. If you want to make a game in Java then use Java. If you want to make one in C++ then use C++. I have no idea how using both and will help you.
agreed. And if you just want C++ for the rendering capabilities, there are libraries out there that already implement the JNI bindings for OpenGL.Quote:

You may want to check out Jake2, a Java port of the Quake2 engine. Most of the 40% slowdown is caused by allocations and calling the OpenGL bindings through JNI.
Either way, I agree with the others. Use C++ or Java, not both :). Although it'd probably be cool to write the map editor in Java.
As long as you use native controls... just please boycott java controls.

Second.
Howbout the best way to communicate c++ and java program,is it rpc-xml???
yeah so nobody accuse me of going off topic,hmmm ;) let say i want to create game A in C++ and game B in java..what library should I use so they both talk to each other???
it's rpc-xml the way to go?
No, that'd be extremely slow. Depends on how much, and how frequently you need to send data between A and B.
The fastest option is still JNI, but it is slow compared to native calls. For example C++ calling a C library function.
JNI i guess is the way to go then...
thanks.
I agree with zacs7 in that you want to be making as few calls through the JNI as possible. Although, unlike everyone else, I don't see why you should not use both C++ and Java.
For anyone wanting to play around with the JNI this Netbeans tutorial got me going with it:

SWT all the way. Native widgets, platform independent, and if a platform doesn't support the widget you want to use it's emulated.Quote:

Java would certainly bring a lot of GUI functionality, however, most in-game GUIs are either using pure Direct3D or they are using some type of flash API. It may actually take more time to streamline and stabilize a C++/Java game than it would just to do it either in pure Java or pure C++.Quote:

So my question to the OP is what is Java bringing to the table that C++ isn't bringing you. Or on the other hand what is C++ bringing to the table that Java isn't?
Before you start some mixed language program it might be a good idea to research the pros and cons of doing so. It could save you tons of dev time and a lot of headaches in the long run.
Yeah, you have a point there. It may not be suitable for the project.
