用字符串java替换字符串

Question

I have a weird problem .

I am calling a web service in my application and the response sometimes printed like this in the console "\\n" now i want to is to replace it with an empty brackets so it will be printed like this ""

so what i have tried

String serverResponse = Util.callService(.....);
System.out.println(serverResponse.replace("\"\\n\"","\"\"");

but the output still prints "\\n" not ""

when i hard code the string , it works

for example

String str = ""\"\\n\""; // equals to "\n" in console 
 System.out.println(serverResponse.replace("\"\\n\"","\"\""); //prints ""

what is the problem ? is it encoding thing ? why the first code does not work with server response ??

Note: I have no control over the web service.

Answer 1

I solve it it requires 4 back slash, not two:

String serverResponse = Util.callService(.....);
System.out.println(serverResponse.replace("\"\\\\n\"","\"\"");
