Foreign Function and Memory API in Java

 Foreign Function and Memory API

Java 16 also introduced a new Foreign Function and Memory API that enables Java programs to interoperate with native code and perform low-level memory operations. This feature is designed to improve the performance and interoperability of Java applications.

Example:

try (var lib = LibraryLoader.load("mylib")) {

    FunctionDescriptor function = FunctionDescriptor.of(C_LONG, C_LONG, C_LONG);

    FunctionHandle handle = lib.lookup("my_function", function);

    int result = (int) handle.invoke(1, 2);

    System.out.println(result);

}
