NO!

C++ and Java are DIFFERENT languages! DO NOT MIX IT!
It's like a vegetarian meal with bacon on top.
A nice piece of chocolate cake with ketchup or
a white shirt that got pink while washing.

DO NOT TRY THIS!

So you can try to compile it :-)

You are a cheater.

No, I'm an eater. :)

Questionable comparisons -- a course of poetry recommended. My 5 for the advice itself. However, something tells be OP might have trouble using this advice, if you understand what do I mean... :-)

"compile with" is virtually impossible because the compiled executables address incompatible targets (Java runs on a virtual machine to be platform independent, C++ not).

Some interoperability is possible via the Java Native Interface that will allow you to invoke DLLs written in C++ or conversely. http://download.oracle.com/javase/1.5.0/docs/guide/jni/index.html[^]. Be ready to swallow technicalities, though.

Another option could be to mix C++.NET code with J#.NET code (both running on the .NET framework), even though J# is not pure Java.

If one of your source file is not too big, consider rewriting in the other language, this may be a faster solution.

Of course you can't compile together Java and C++, however, you may call C++ code from Java and the opposite, using JNI, see, for instance, here[^].

I'm actually doing on a program for face recognition.
but for the face detection part i'm using java for the coding while the rest of the portion is on c++. so is there any way to do that?

TorstenH. 5-Aug-11 5:25am

why do you use c++ "for the rest" ? wasn't complicated enough to do it all in java? change it. Use C++ OR Java. not both.

Sergey Alexandrovich Kryukov 5-Aug-11 7:06am

Well, this is a sound advice, I kind of agree. However, as CPallini pointed out JNI can help. I would advise to use it as a last resort though.

TorstenH. 5-Aug-11 7:11am

no, that can't be true.
What is this C++ Java mixing thing? Are the C++ people bored of their stuff? is it a new "I can do both" thing?
From a developers point of view it's total bullsh*t! Stuff that one not just goes to hell for but also has to do VB for eternity.
