Avoiding multiple If statements in Java

Question

I\'ve coded a method something like this. But I guess this should undergo refactoring. Can any one suggest the best approach to avoid using this multiple if statements?

Answer 1

There is no way to evade that in general. In your case - if there is a set of allowed extensions - you could create an Enum, convert the extension to the Enum type via valueOf(), and then you can switch over your enum.
