To make things worse, the parent class usually defines at least part of the behavior of the subclass, and any changes to the parent class can affect the behavior of the child class. If the inherited implementation is not suitable

adduser () method can be defined as public Boolean adduser (userdto user). In the iuserdao method, adduser () the object of the userdto type is used as a parameter, so there is a dependency between iuserdao and userdto.

there is no loop in the instance diagram. In other words, it can only be a one-way relationship. Figure F Synthesis (composition) Synthesis ( fig. G) is a special form of aggregation, implying "local" within the "whole" life-cycle responsibility. Synthesis is also not shared. Therefore, while the part does not necessarily have to be destroyed with the destruction of the whole, the whole is either responsible for maintaining a partial survival state o
