[talhamasood]

Brilliantly explained and it will really help if you’ll keep making videos in this pattern where you show real life example then practically do it .... thanks

[md.emranhossain]

Please make tutorial on other design patterns. (like: Singleton Patterns, Proxy Patterns, Decorator Patterns, Adapter Patterns, Abstract Factory, Interpreter Patterns Patterns, Factory Method Patterns) more or less please cover "Gang of Four" Design Patterns by Java.

Good tutorial!
Just one little point, if you check if two Strings are equal then use .equals instead of .compareTo, because it is better performance wise and also easier to read for others

[dejancetkovic]

Hey,
Thank you very much for the video. One quick question: the reason you are using type object is the update method is because you might going to have a Shop subject later on or other subjects right? So I'm guessing one solution to this problem is to have a method like yours and use if statements inside, or to have the update method overloaded right?

Do you have the code files for this? If you could upload them on github that'd be great.

[ankitg]

Thanks, man! I tried the same but when I am passing 'Chris' in the mail object, then it is not working.
