JNI: A Fast and High performing Programming Framework

JNI is an acronym for Java Native Interface. It is a programming framework that enables java code running in a Java virtual machine to call and to be called by native applications and libraries.    

Goal: Binary compatibility on a given platform of native method libraries across Java Virtual Implementations.  

But what actually JNI is?

A set of tools that let user to call native methods.

An interface where data is passed to/from C/C++ methods.

A programming framework that enables to write native methods when an application cannot be directly written on the Java programming language.

Make another existing programming application compatible to run on Java application by changing the language.

This framework lets native method use objects same as Java code uses.




Fast i.e time critical calculations.

Add functionality to Java applications.

High performance

Platform-sensitive API implementation.

Improve efficiency of integration

Role of JNI:

Being a two-way interface, it allows Java applications to invoke native code and vice-versa.

Handle situation where Java applications combine with native code.

Supports two types of native code: native applications and native libraries.

Owing to its ability to add functionality to the Java applications, this is also referred as the escape hatch.

Steps involved in using JNI:

Java code:  In this one can write and compile the Java code by declaring the native method and ensuring that a shared library is loaded before the native method is called.

Creating C header file:   In this step one can create a header file of C that features function prototype for native methods.

C implementation: With the aid of mangled names and extra parameters one can write a C implementation of native methods.

Compiling: Compiling of C code and creation of shared library takes place in this step. Moreover each library features lib prefix in front of it.

Execution:  Execution of the Java program.

So, whether you are looking for the used JNI or New JNI, go for the MCA Computer Corporation. This extensive line of this offers a reliable, fast and high performing JNI. All these JNI features a warranty of 1 to 5 Years.
