JNI Explained: Java Native Interface Guide

JNI, short for Java Native Interface, is a mechanism provided by Java for implementing native method calls. With JNI, Java code can call native (C, C++, etc.) code, enabling interaction between Java and other languages. JNI is particularly useful in scenarios where interaction with hardware or specific operating systems is required, such as image processing, audio processing, network programming, etc. By using JNI, Java programs can call native code to achieve more efficient and flexible functionality.
