String replace not working, even after assigning to another variable

Question

Java String.replace not working even after assigning to a variable.

I have a JSON formatted string like as follows.

{"Obligations":["\nAggregate","\nDelay"],"Result":"Permit"}

I want to remove the \n from the string.

I used the following piece of code. There is no difference.

    String test =jsonObject.toString().replace("\n", ""); 
    System.err.println(test);

But I get the same result. Is there something wrong in it ?

Does [this answer](https://stackoverflow.com/a/1166912/4852017) provide any assistance? — ZeldaZach, Jun 22 '17 at 19:04
`\n` matches a literal new line. `\\n` matches the String pattern `\n`. — Compass, Jun 22 '17 at 19:06
`.replace("\\n", "");`. Backslashes need to be escaped in string literals. — JB Nizet, Jun 22 '17 at 19:06

"\n" means a new line. You must use an escape.

Try it:

String test =jsonObject.toString().replace("\\n", "");

This works.

String test =jsonObject.toString().replace("\\n", ""); 
System.err.println(test);
