Had heard reflection self-communion and reflex should be one and the same only in Java Whatwhat is written reflection self-communion and reflex hearing of only in Java should be one and the same I feel is one and the same those who hope somebody can point out them is different Self-communion is introspective, introspection is in reflection bag, use reflection implementation, introspection can be pair of catoptric augment, both is not a concept.

java中只听说过反射自省和反射应该是一回事吧 whatwhat 写道java中只听说过反射自省和反射应该是一回事吧我感觉是一回事希望有人能指出它们的不同自省就是内省，内省在反射包里，是利用反射实现的，内省可以算是对反射的扩充，二者不是一个概念。
