How to convert a char to a string in Java

Problem
I have a char and I need a String.

1 2	char c = 'a'; String s = c;

But eclipse complain it has compile error : Type mismatch: cannot convert from char to String

Solution
String concatenation can fix this type mismatch error:

1 2	char c = 'a'; String s = "" + c;
