Java Native Interface (JNI)

Java Native Interface (JNI) is a framework that allows Java programs to interact with code written in other programming languages like C or C++. It enables Java to access system-level features, optimize performance, or reuse existing native libraries that aren't written in Java. JNI acts as a bridge, translating requests between Java and native code, ensuring they work together smoothly. This capability is useful when Java alone can't perform certain tasks efficiently or when integrating with legacy systems, providing flexibility while maintaining Java’s platform independence.
