Absolutely. For example, the jBoss EJB container uses reflection to
invoke the methods on the EJB instances, and the performance is very
nice. And as James suggests, we store the methods in a hashtable for
fast access.
So:
1. Method invocation using reflection is fast
2. Method lookup from java.lang.Class is slow
Use intelligently and it is ok.
