Swing GUI calling C++... Is this efficient?
 

Im building a Swing GUI that will parse multi table tournament summaries, have a hand replayer, and also pokerstove-esque EV calculations via hand ranges. I know basic-intermediate C++ and Im completely new to Java. On advice from my cousin, a senior programmer, and all around nerdy badass, Im attacking this from a "Swing GUI that will call on C++ for calculations" angle.

However, in trying to learn Swing, Im finding out Im going to have to become at least as good at Java as I am at C++. So, Im wondering if I couldnt build it all in Java, as a more efficient method.

Thanks for the input... and as for the cryptic title, I only wanted people to look at it who would understand my question.
haha

Is there a reason why you think C++ would be significantly more efficient than Java at the calculations you are planning? If not, do it all in Java. It'll be a good learning exercise.

I agree.. i cannot see a significant improvement in using jni to call a c++ backend (if any). The old Java-is-too-slow-for-anything argument doesn't hold up anymore.

Just my 2c. [img]/images/graemlins/smile.gif[/img]

Good luck!

Yes, build it all in Java. Java is not slow. Good luck!

actually I just did it at the suggestion of my cousin, who I found out is just used to doing it that way. well Im committing to Java, and I've been using an online tutorial, I guess thats the best way to start?

thanks for the help... this language is sooooo less...... cryptic!

Haha, yes it can be less cryptic but it also has many traps for c and C++ programs. Oh well. I only use calls to outside functions when I absolutly have to (suprisingly more often than you would think). Java has really picked up in speed, my one complaint is still that there is not a great visual development environment, but then again I can't take VB to a linux box can I?

{Yes I know there are attempts at making a vb like language for linux, please I'm just trying to make a point in my simple minded little way.}

dont be talkin mess about my beautiful beautiful swing!!

eclipse is just about the coolest editor ever.... so leet.

Re: Swing GUI calling C++... Is this efficient?
 

Yes, Swing will be fine. I just finished the first version of a replayer, and I wrote it all in Java, with Swing for the GUI. If you'd like to check it out, look here

PartyMine is implemented in this exact same way. I have a Java Swing client and use JNI to talk to a core DLL that does the low level Win32 calls that Java cannot do.

If you don't need to do very windows specific stuff I would not use C++ at all.

JNI can get slow if you are moving large pieces of data between the two.
