Is there a way to judge if a class has been loaded into the jvm?

Is it possible to determine if a class is loaded in jvm? In my opinion, I think that's the way to go findClass

, right?

Enable classloader logging with -verbose:class

and read the log.

Ok, so I didn't. But it looks like it will be possible in the Instrumentation APIgetAllLoadedClasses()

.

But then you still need to start the JVM with agent

.
