Convert JSON to Class

Some heroes have given themselves the task of creating libraries capable of doing that in JAVA.

I share the following link JAVAToJSON where you can review the libraries that I mention. That way when you receive the JSON you can convert it.

If nothing else you need the class, you would stay like this:
