The Java Native Interface (JNI) is a native programming interface that is part of the Java Software Development Kit (SDK). JNI lets Java code use code and code libraries written in other languages, such as C and C++.The Invocation API, which is part of JNI, can be used to embed a Java virtual machine (JVM) into native applications, thereby allowing programmers to call Java code from within native code.his tutorial will walk you through the steps of using the Java Native Interface. You'll learn how to call native C/C++ code from within a Java application and how to call Java code from within a native C/C++ application.
(However, you can compile code written in other languages into Java bytecode.) For a description of the JVM see: . The Java Virtual Machine Specification .. The Java API is the set of classes included with the Java Development Environment. These classes are written using the Java language and run on the JVM. The Java API includes everything from collection classes to GUI classes. You can view a complete listing of the Java API at:  Java 2 Platform, Standard Edition, v 1.3.1 API Specification ..
