Hi all, Could someone explain the Polymorphism to me with some examples? I really want to know the definition of Polymorphism and how we can use it. Thank you in advance. Mike

Def.: ability of an obj to respond to a message in a manner appropriate to its type. Ex: In this example, you could see which method gets called. The method of the class to which the object belongs to gets called.
If you are familiar with C++ the same is achieved using the keyword virtual. Regds. - satya
hi mike polymorphism is a oops concept where function/object act differently according to the situations for example add(int a,int b); add(int a,float b); add(double d,double x); see here add function will act differently according to the parametes passed to the add function this is checked only during runtime. it is taken care by jvm this in brief polymorphism hope i am clear if not please get back regds thejus/mahesh

Hi All, Polymorphism:One or more object act diferently for same message. Take one real world example Suppose one Car (Car Object) , one Cycle (One more object) are running on the road and they reached a signal and with red sign both object will stop. Here both objects are stopped for one message but the mechanism is different. I hope it is clear for you.............
Please notice that there are two types of Polymorphism Viz 1) Static Polymorphism and Dynamic Polymorphism or 2) True Polymorphism or False Polymorphism or 4) Compile Polymorphism or Runtime Polymorphism
