Try … catch … finally return value

Question

I found that it\'s a shame that I can\'t return a return value from a such simple construction as try ... catch ... finally

 def foo: String = {
            


        

Answer 1

This method returns a Unit; you have to return something in the catch block; or I'd rather suggest to change the return type to e.g. Option; or use Try class.

What is obvious - you don't always have a string in this situation. In Java people tend to ignore the realities, but this is Scala, one can do better.
