In the OCP book :
by Jeanne Boyarsky and Scott Selikoff it is said that this command will be used to enable assertion for classes in the package and sub-package :
(Chap6 is the package name and AssertionTest is the class name that contains a main function), however when I execut this code I get an error telling that the class AssertionTest is not found.
Does anyone detected what I missed ??
