simple.Jsonarray for json.Jsonarray

Question

I have a problem. In the same code, I kind of need to use both simple.Jsonarray and json.JSONArray. I can’t import both, so I’m trying to use the simple. It turns out that when I do a request, the answer is a json that java says is simple, so I can’t use the other.

In the excerpt of the code I’m having problems, I’m reading a file. It comes back as an Object, which I need to turn into json. follows the excerpt:

JSONParser parser = new JSONParser();
JSONArray queues = (JSONArray) parser.parse(new FileReader("file.json"))

The following error appears (in the first line of the above section):

java.lang.ClassCastException: org.json.simple.JSONArray cannot be cast to org.json.JSONArray

If I use the simple of the problem elsewhere in the code. I am using mvc, so it is difficult to create a new file just to make a method...

You can import and use both yes. Just import normally and, when using the code, pass the complete reference, including the package path. Something like:

org.json.simple.JSONArray json = new org.json.simple.JSONArray();

If, in another code location, you need to use the other Jsonarray class, you just need to pass the full reference. For example:

org.json.JSONArray json2 = new org.json.JSONArray();

As for your current code, there is nothing to do. The casting error is quite clear.
