Java 9에서 클래스로더가 있는 모든 모듈을 어떻게 표시할 수 있나요?

import static java.util.Objects.isNull;

public class Java9ClassLoaderTest {
   public static void main(String args[]) {
<strong>      ModuleLayer </strong>layer = <strong>ModuleLayer.boot()</strong>;
      layer.modules().forEach(module -> {
<strong>         ClassLoader </strong>classLoader = module.<strong>getClassLoader()</strong>;
         String classLoaderName = <strong>isNull</strong>(classLoader) ? "bootstrap" : classLoader.<strong>getName()</strong>;
         System.out.println(classLoaderName + ": " + module.<strong>getName()</strong>);
      });
   }
}
