Removing "\" in json object string

Question

How can i remove special character "\" in the string below:

String x = {
    "message": {
        "@content": "toom"
    },
    "recipients": "[{\"@id\":\"1000001865\"}]",
    "room": {
        "@subject": "room"
    }
}

I used x.replaceAll("\\","") but it does not work.

technically x is not a String in your example. Why exactly doesn't `replaceAll("\\","")` work? any exceptions? — GameDroids, Feb 05 '14 at 04:34
You don't want to do that. Instead, parse the nested string as more JSON. — SLaks, Feb 05 '14 at 04:34
@GameDroids: No; it's a syntax error. And that (a) won't work (regex) and (b) is wrong anyway (JSON parser) — SLaks, Feb 05 '14 at 04:34
Can i know the Purpose behind doing this ? May be we can provide a better way to what you want to achieve. — Chintan Soni, Feb 05 '14 at 04:39

You must escape the backslash in the regex.

try

x.replaceAll("\\\\", "")

see JavaRegularExpressions: 3.6. Backslashes in Java
