Java for C++ is a tool that generates C++ wrapper classes for existing Java classes. It reads a list of Java class names and creates source code for C++ classes to wrap them. The implementation of the wrapper classes uses JNI (Java Native Interface) to call the "real" Java classes. The C++ API to use these wrapper classes is very close to the API of the original Java classes, so developers of C++ software can use Java classes as if they have been implemented in C++.
