Testing code that utilizes the Foreign Function & Memory API (Panama) in Java involves techniques to ensure memory safety and correct function calls between Java and native libraries.

    // Example code demonstrating the usage of Foreign Function & Memory API
    import jdk.incubator.foreign.*;

    public class ForeignFunctionExample {
        public static void main(String[] args) {
            // Load the native library
            LibraryLookup library = LibraryLookup.ofDefault();
            SymbolLookup symbolLookup = library.lookup("nativeFunctionName");
            
            // Define the foreign function signature
            MethodType methodType = MethodType.methodType(int.class, int.class);
            
            // Call the foreign function
            Invoker invoker = CLinker.getInstance().downcallHandle(symbolLookup.lookup("nativeFunction").get(), methodType);
            int result = invoker.invoke(10);
            System.out.println("Result from native function: " + result);
        }
    }
