1st Answer Example
"Native languages such as C or C++ interfaces with Java code via the Java native interface, or JNI. This framework enables application developers to write native code if necessary, such as when application components can't be written using Java. JNI is part of the Java Development Kit, or JDK, and assists the developer with interfacing with any native code."

2nd Answer Example
"Developers who use Java can interface with any native code, including C or C++ through the Java Native Interface or JNI. This component of the Java Tool Kit provides the programmer with tools and library routines that can be used to develop portions of the application which either need to interface with native code or can't be written in Java. Developers can also use JNI to modify existing applications that were originally written in native code."
