Hi,

I read an article and found this code.







What does it meant? What is the meaning of ? What is the advantage of doing so?



Thank you

This is referring (I assume) to the facade design pattern. Here are some articles on it:

This is one of the classic GOF design patterns. It's intent is to simply a more complex class to make it easier to use. Hopefully this will be helpful in answering your questions.
