The “Foreign Function and Memory API” (FFM), previewed in Java 20, allows Java programs to interoperate safely with code and data outside of the Java runtime. In this fast-paced talk, we will explore what the FFM API has to offer and, via a hands-on live coding example, see how the promises of FFM can be realized in your code today. The live-code example involves integrating and using a native system call directly from Java.
