Java Native Access (JNA)
Java Native Access (JNA) is an intermediate, 8-week course for developers who already know Java, basic C types and native process concepts. It teaches mapping a small C API into Java with deliberate ABI mapping, structures, pointers, callbacks, and memory ownership across the Java/native boundary, culminating in a Java wrapper project around a small native measurement library.
Map a small C API into Java with deliberate ABI, memory ownership and error handling.
