Replace dot in a String.

[dmjpro]

I want to replace dot in a String.
I used String.replaceAll ..but due to regular expression .... I couldn't find out the solution.
I used String.replaceAll(".","something");
But in regular expression "." has a special meaning .....

A backslash removes any special meaning from regular expression (meta) characters
so feed it a \. (backslash dot). Note that if you want to construct a literal String
for that you need to escape the backslash again to keep javac happy, so you
need to type "\\." (backslash backslash dot).

kind regards,

I think I've posted the following comment a hundred times in various forms, but here goes #101: don't let String's replaceAll blind you to the existence of String's replace: it is a simpler version that doesn't involve regular expressions, so you don't have to wring your hands with worry about special regular expression characters. Calling it is easy:

String result =s.replace(".", "something");

Yes, it does replace *all* instances of '.' with 'something':

Replaces each substring of this string that matches the literal target sequence with the specified literal replacement sequence.
