Backslashes not able to remove from String

Question

       byte[] jsonData = Files.readAllBytes((Paths.get("txt.json")));

        String data = new String(jsonData,"UTF-8");
        data= data.replaceAll("[\\r\\n]+", "");
        data= data.replaceAll("\\t", "");

        data= data.replaceAll("\\\\","");
        response.setResponse(data);

data i am getting like this

       \"abs\": \"abc\",\"dff\": [{\"dff\": [{\"rtr\": \"dfg\",\"fdgdfg\"

but i need to remove slashes

        "abs": "abc","dff": [{"dff": [{"rtr": "dfg","fdgdfg"

please Help me what changes i need to do

Stop. What is the content of `txt.json`? Why do you need to replace escape characters? — OneCricketeer, Dec 15 '16 at 07:13

**How** are you "getting like this" ? Are you printing it on the console? Or are you using a json library to output it as JSON? (Or something else) I'm guessing you're outputing it using a JSON library as a string, which will add the backslashes back in, logically, to make it a valid json string. — Erwin Bolwidt, Dec 15 '16 at 07:14
txt.Json File is JSON file, i am trying to read from json file and convert to String — user3639244, Dec 15 '16 at 07:39

{ "abc": "fgf", "fbdf": [{ "fdgdfg": [{ "fg": "gfdf", "fdgd": "dfgUs:"}, { "fidfg": "contafdgber","lafdgel": "(800) 206-9469" }], "ldfg": [{ "gfdd": "fgdfel", this is Txt.JSON — user3639244, Dec 15 '16 at 07:47
I have tried all methods , and Previously asked questions, but Slashes still displaying — user3639244, Dec 15 '16 at 07:51
i need to attach it into a JSON response, that is why i am trying to convert to string and attaching to JSON Response, is this the right Way? or how can i read from ?JSON file and attach it to a JSON response? — user3639244, Dec 15 '16 at 07:56
Show the real code that generates the output. We don't know what you mean with "attaching to json response". What kind of object is `response` on which you call `response.setResponse` ? What do you do with this `response` to get the output that you're showing above? — Erwin Bolwidt, Dec 15 '16 at 09:45

Use replace() instead of replaceAll():

data = data.replace("\\","");

Any particular reason? – shmosel Dec 15 '16 at 07:13
Of course: replace() is a simple string replacement. replaceAll() uses regular expressions. – Christian Dec 15 '16 at 07:16
But how does that answer the question? – shmosel Dec 15 '16 at 07:17
easier to read than `replaceAll("\\\\", "")` and probably more effecient – Scary Wombat Dec 15 '16 at 07:19
He wants to remove all backslashes, doesn't he? Backslash is an escape character in regular expressions. – Christian Dec 15 '16 at 07:40

@Christian Yes, and that's why the OP already escaped it. This solution is no different than what the OP is already doing. And ScareWombat, it's not more efficient (in all current Java versions) - because String.replace invokes String.replaceAll, after escaping all characters that need to be escaped. – Erwin Bolwidt Dec 15 '16 at 07:49
