How to used JAVA code in C++.

[Abhinay]

hi,

I am new in C++ programing and I wanted to know that is there any way to use java code in C++, I am somewhat familiar with "JNI" but using JNI we can use other ( C++ ) code in java reverse is not true.

Please suggest me.

Thanks in advance,
Abhinay

Um, JNI allows you to use Java code in C++, not the other way around. I don't think there's any way to use C++ inside the JVM, though you could of course spawn a child process.

Generally, you cannout use Java code in C++. While the two languages appear similar in syntax they are really quite different and behave differently.

Such as:
1) no delegates in C++
2) Java methods become C++ inline functions
3) Java calls do not make a copies of the objects used on the call
4) there are no functions in Java. There are only methods of classes
5) Java is an object oriented language. C++ is a structured language with some object oriented features.
6) etc...

Sun designed Java to look like C++ in order to get C++ developers to abandon the public C++ in favor of Sun's proprietary Java by promising that Java didn't require nearly the skill to use as C++ but still didn't require the C++ developer to fundamentally abandon the familiar syntax of C++.

You can go both ways using Java and C or C++. You can call C or C++ functions
from Java using JNI and you can also start the JVM from C or C++ and make Java
call C or C++ functions again using that same JNI framework. C or C++ functions
can call Java functions at will. Read the JNI documentation.

Of course you can't mix those languages by using both in a single compilation unit.

kind regards,
