Java Native Access (JNA) is a community-developed library that provides Java programs easy access to native shared libraries without using the Java Native Interface (JNI). JNA's design aims to provide native access in a natural way with a minimum of effort. Unlike JNI, no boilerplate or generated glue code is required.
In software design, the Java Native Interface (JNI) is a foreign function interface programming framework that enables Java code running in a Java virtual machine (JVM) to call and be called by [1] native applications (programs specific to a hardware and operating system platform) and libraries written in other languages such as C, C++ and assembly.
The first Java GUI toolkit was the Abstract Window Toolkit (AWT), introduced with Java Development Kit (JDK) 1.0 as one component of Sun Microsystems' Java platform. The original AWT was a simple Java wrapper library around native (operating system-supplied) widgets such as menus, windows, and buttons.
Note: Downloading and installing of Java will only work in Desktop mode on Windows 8. If you are using the Start screen, you will have to switch it to Desktop screen to run Java. Windows Server 2008/2003; Intel and 100% compatible processors are supported; Pentium 166 MHz or faster processor with at least 64 MB of physical RAM; 98 MB of free ...
A similar function to create a native executable from a Java application is provided by the native-image tool of standalone GraalVM releases. The tool processes a Java application's classes and other metadata to create a binary for a specific operating system and architecture. It can be used to build a native executable or a native shared library.
The Java platform is a suite of programs that facilitate developing and running programs written in the Java programming language. A Java platform includes an execution engine (called a virtual machine), a compiler and a set of libraries; there may also be additional servers and alternative libraries that depend on the requirements.
idlj – the IDL-to-Java compiler. This utility generates Java bindings from a given Java IDL file. jabswitch – the Java Access Bridge. Exposes assistive technologies on Microsoft Windows systems. java – the loader for Java applications. This tool is an interpreter and can interpret the class files generated by the javac compiler.

[68] [69] [70] Java Native Access (JNA) provides Java programs easy access to native shared libraries (dynamic-link library (DLLs) on Windows) via Java code only, with no JNI or native code. This functionality is comparable to Windows' Platform/Invoke and Python's ctypes. Access is dynamic at runtime without code generation.
