Replace [] with () in a String

How can I change a String like this:

[a,b,c]

to this:

(a,b,c)

I want to use Java's regular expressions.

If your problem is just these parentheses, something like this could suffice:

s.replaceAll("\\[", "(").replaceAll("\\]", ")")

Actualy you can do this by invoking replaceAll once

"[a, b, c]".replaceAll("\\[([^\\]]+)\\]", "($1)");
