Hi,
In my project I have encountered a situation where given an input functionality varies.
So I have though of two ways for dealing with this situation. Both work but want to choose one.
First Method:
Using a Enum where given an input and depending on enum output I will handle the business login. Also I have handled the exception saying if there is no enum for that particular type I will return null.

Second Method:
Using HashMap which gives the value when given a key. And using that value will build the business logic.

There are even many ways like using if-else, switch-case etc.
Can someone help me in choosing why I should go with a particular implementation.
My team lead says hashmaps because of performance but there will not be more than 5 types.
I prefer enums because of the readability.

So thats where I am thinking, what to go with. Any suggestions??

This is an incredibly vague description of your problem. Maybe you can give us more background on what it really is that your business logic is about.
