How to split a string when elements in the string can contain the delimiter

Question

I have a string like that:

String s = "{"Player":{"id":"1","name":"PM001"}},{"Player":{"id":"2","name":"PM002"}}"

I want to omit the "," so the result should be :

{"Player":{"id":"1","name":"PM001"}}

{"Player":{"id":"2","name":"PM002"}}

It looks like a json object. Have you already tried the json-Api for Java to extract the elements? — Reporter

JSONArray newArray = new JSONArray(s);
newArray.get(0);
newArray.get(1);

Thanks for ryour reply, but an error occured "Cannot instantiate the type JSONArray"

What is the return Object of s ? String or what?

If it is not work set this String to JSONObject and call getJSONArray

I would just split on a comma surrounded by reversed curly brackets:

String[] parts = s.split("(?<=}),(?=\\{)");

This uses look arounds to assert the presence of, but not consume, the curly brackets.
