Is concatenating with an empty string to do a string conversion really that bad?

Question

Let\'s say I have two char variables, and later on I want to concatenate them into a string. This is how I would do it:

char c1, c2;
// ...

Str         


        

Answer 1

I prefer using String.valueOf for single conversions - but in your case you really want concatenation.

However, I would suggest that this version would remove all potential ambiguity:

String s = c1 + "" + c2;

That way there's no possibility, however remote, of someone considering whether c1 and c2 will be added together before the concatenation.
