The code you quoted is not the solution, it's the original, unrefactored code. The solution uses polymorphism instead of the switch statement.

i got a bit confused (because i read some lines not properly). it makes sense now. of course payAmount() gets declared abstract in the superclass, subclasses implement it and switch statement gets kicked out.
