Class ForeignFunctionMemorySecondPreviewNotes

java.lang.Object
net.jrodolfo.java_evolution.java20.ForeignFunctionMemorySecondPreviewNotes
public class ForeignFunctionMemorySecondPreviewNotes extends Object
Explains the Foreign Function and Memory API second preview in Java 20.

Java code has long been able to call native code through JNI, but JNI is difficult to use safely and cleanly. The Foreign Function and Memory API aims to provide supported native calls and off-heap memory access with clearer Java-level APIs.

Java 20 was still a preview release for this API, so this repository avoids a native-code example and keeps the focus on the problem the feature solves.
