JSON Object creation fails when instantiated with a string with backslashes

Question

I have code, where I instantiate a JSONObject from a string. Upon instantiation, I get a JSONException Illegal escape. Any pointers on how to resolve this ? Here is the block of code: ``` @Test public void testJSONString() { try { String str = "{"path":"folderA\myfileA"}"; JSONObject jsonObj = new JSONObject(str); } catch (JSONException e) { e.printStackTrace(); fail(); } } ``` The exception I get is: ``` org.json.JSONException: Illegal escape. at 18 [character 19 line 1] at org.json.JSONTokener.syntaxError(JSONTokener.java:433) at org.json.JSONTokener.nextString(JSONTokener.java:289) at org.json.JSONTokener.nextValue(JSONTokener.java:360) at org.json.JSONObject.(JSONObject.java:225) at org.json.JSONObject.(JSONObject.java:327) ``` Seems to be an issue with the `\m` there. What would be the right way to escape this ? Thanks!

Accepted Answer

The json should escape the backslashes like `\` so in Java both backslashes need escaped `\\`.

```
String str = "{"path":"folderA\\myfileA"}";
```
