Java Native Interface

The Java Native Interface (JNI) is a framework that allows Java programs to communicate with and use code written in other programming languages, like C or C++. Since Java is platform-independent but sometimes needs to access system-specific features or optimized libraries, JNI provides a way for Java to interact with native code securely and efficiently. Think of it as a bridge that enables Java to utilize specialized or existing native functions, giving developers more flexibility without sacrificing Java’s portability and safety features.
