according to Java Annotation API:
RetentionPolicy.CLASS Annotations are to be recorded in the class file by the compiler but need not be retained by the VM at run time.
RetentionPolicy.RUNTIME Annotations are to be recorded in the class file by the compiler and retained by the VM at run time, so they may be read reflectively.
I am looking for a sample of "CLASS" retention policy. when we need to use this policy instead of RUNTIME policy.
