Is Switch (Case) always wrong?

Question

Are there instances where switch(case) is is a good design choice (except for simplicity) over strategy or similar patterns...

Answer 1

Use Switches when you're testing on values of primitives. (ie. integers or characters).

Use polymorphism when you are choosing between different types.

Examples : Testing whether a character the user has entered is one of 'a', 'b' or 'c' is a job for a switch.

Testing whether the object you're dealing with is a Dog or Cat is a job for polymorphic dispatch.

In many languages, if you have more complicated values you may not be able to use Switch anyway.
