JNA
Java library providing easy access to native shared libraries without requiring JNI or native code.
What is JNA?
Java Native Access (JNA) is a Java library that allows Java programs to call native shared libraries directly using natural Java method invocation, without requiring JNI or native code. It solves the problem of accessing platform-specific native functionality from Java by providing a simple interface to describe native functions and structures, making integration seamless and reducing development overhead.
Java developers who need to interact with native system libraries, hardware APIs, or platform-specific functions without writing JNI code, particularly those building cross-platform applications or integrating with existing native codebases.
Developers choose JNA because it eliminates the complexity and boilerplate of JNI, offering a more straightforward and maintainable way to access native libraries. Its ease of use, automatic type mapping, and extensive platform support make it a preferred alternative for native integration in Java projects.
