I have this variable in scala with
val id: Option[(String, JsValue)]= Some((studentId,{"courseId":"765"}))
I want to retrieve that id 765 but I am not able to make it happen. Thank you in advance.

What did you already try? BTW, there is no JsArray in your code... – cbley Jan 02 '20 at 08:08

Please refer this to know more about play json basics.
Here is a quick but dirty way
val cid = id.map{ jscid => (jscid._2 \ "courseId").as[String]}.get
It will give you
cid: String = 765.
Beware of .as and .get . Put your validation and error handling.

@cchantep: I agree. Pattern matching (or some other way) should be used and error should be handled as per requirement. I have put a warning. – asanand Jan 02 '20 at 08:50
