Solution: The Chain of Responsibility pattern
(upbeat music) - [Instructor] Now let's have a look at my solution to this exercise. So, first of all, in my AuthenticationHandler class I've created a constructor. This takes another AuthenticationHandler as an argument and inside the constructor I'm assigning that to a field called next. In the handleRequest method I've got a condition that checks if next is no and if it's not, then I call the handleRequest method on the next variable. This is how requests will get passed along the chain. Next let's take out a concrete implementation of this class. So if I go to basic AuthenticationHandler, I can see that I've got a constructor and this takes an AuthenticationHandler as an argument too and then it calls super and passes in this Handler. In the handleRequest method, I have a condition to check if the requestType that's I'm passing in is equal to basic and if it is then I go ahead and print out Handling basic…
