String replace a Backslash

Question

How can I do a string replace of a back slash.

Input Source String:

sSource = \"http://www.example.com\\/value\";

Answer 1

s.replaceAll ("\\\\", "");

You need to mask a backslash in your source, and for regex, you need to mask it again, so for every backslash you need two, which ends in 4.

But

s = "http://www.example.com\\/value";

needs two backslashes in source as well.
