What Is Jni? |
|
Answer» JNI stands for Java Native Interface. It is an interface between Java, applications and libraries that are written in other languages. JNI is solely used to INTERACT with “native” code (code written in SYSTEM level LANGUAGE such as C). For instance, JNI enables the usage of C libraries and C PROGRAMS to be used in Java programs.

Define Jni Functions And Pointers? |
|
Answer» JNI functions are those which are used by the developers to interact with JVM within a native method. EVERY JNI function receives a special PARAMETER as its first ARGUMENT – JNIEnv ; which points to a special JNI data structure of the type JNIEnv_ . One of the elements of JNI data structure is a ‘pointer to an array’ generated by JVM, and each ELEMENT of this array is again a pointer to a JNI function. A JNI function can be invoked from the native method by referencing these pointers. Every JVM provides a unique implementation of the JNI functions.

What Is Native Interface In Java? |
|
Answer» JNI is the mechanism used to INVOKE methods WRITTEN in languages such as c and C++. You can WRITE code using language like c and c++ and declare its native methods and can USE the same method in java using JNI. JNI exposes JNI functions and pointers that can access java objects and methods. JNI is the mechanism used to invoke methods written in languages such as c and C++.
