How to generate Java classes from Json File?

Question

I would like to knows if someone can show me the right way to generate Java classes from a json File ?

for example if we have the following json file :

{
  "Personne": {
    "Name": "Job Moun ",
    "Phone": "062352665566"
  }
}

I want to generate Java code automatically, something like that :

public class Personne{

private String Name;
private String phone;

....
}

There are many (online) tools available. Example: http://www.jsonschema2pojo.org/ — User404, May 06 '15 at 08:42
Lots of frameworks exist that will solve this problem for you. Jackson ( https://github.com/FasterXML/jackson ) and GSON (https://code.google.com/p/google-gson/) are both worth looking at and both make this pretty easy. — DaveH, May 06 '15 at 08:44
@yahyaelfakir generate a class file not the object, read the question — Olayinka, May 06 '15 at 08:53
It's not as simple as your example, but Swagger has quite a few export options once you define the objects: http://editor.swagger.io — HairyFotr, May 06 '15 at 11:50
If you have node.js and npm installed, you can take a look at this package: https://github.com/rtoshiro/json2poxo — Hamiseixas, Aug 31 '15 at 16:39

You can have a look at this online tool if it's sufficient for you:

or use some templating engine like Velocity in conjunction with Jackson library for reading JSON. Here you have some basic functionality:
