I want to replace the fist word to then second.

"dd" --> \"dd\"

I try s.replace('\"','\\\"'); It doesn't work.

How to do it ?

Thanks

The backslash is special to both the Java compiler and the regexp parser, which means that to specify a real backslash in a regexp, you have to actually write four backslashes: Two of them (\\) are needed by the regexp, and then to get the Java compiler to parse those two, they have to be escaped, giving you four. So I believe your replacement expression ought to have five backslashes, total: "\\\\\"" .
