How to parse class object to json and json to class object again using java?

Question

In my project I have two classes: TourManager and City. TourManager class has and array and a method called add.city() where I put the created cities. 

 TourManager tour = new TourManager();

 City city25 = new City("Maia", 100, 95);

 tour.addCity(city25); 

1) How can I parse the tour object with the cities added to jsonObject and send to custom code?

2) In my custom code, I also have a TourManager class, and I need receive the json request and parse the json object to TourManager again to do some processing. Is it possible to do that?

Hi Feilpe Santos,

Greetings from ShepHertz!!!!

Here are the way around to achieve your goal.

• Creating JSON Request from class : You can create a method in your TourManager class that will create a Json from class members with respective keys if class contains array or array List you can use JSON Array for that.
• Parsing Response From Json to class Object : Once you will receive response from custom code server, you can create another method in your TourManager that will generate class object with the help of your JSON response

Let  me know if it helps.
