How to split a JSON message and convert it to a Singleton class

Question

I'm new using this especial classes. My problem is:

I recieve in a variable this JSON message:

String buffer = stringBuilder.toString();

String Buffer is this information. It has a list of empresas (Bussiness) and one parameter is a List of Proyects(that has two variables: money and information).

[
    {
        "name": "LOL",
        "address": "LCS",
        "phonenumber": 98987845,
        "email": "david@gmail.com",
        "creditcard": "7674774",
        "proyects": [
            {
                "money": 30000,
                "information": "This is my proyect",
                "id": 1
            },
            {
                "money": 0,
                "information": "My second proyect",
                "id": 2
            }
        ],
        "id": 1
    },
    {
        "name": "UPC",
        "address": "Castelldefels",
        "phonenumber": 93245098,
        "email": "aasasaasa@gmail.com",
        "creditcard": "asdfg9876",
        "proyects": [],
        "id": 2
    }
]

So then i create 3 java.class: For example the class User is the following:

package com.example.david.dhl;
import java.util.List;

class User {

    static String name;
    static String password;
    static List<Empresa> Empresas;

    private static final Usuario ourInstance = new Usuario();

    static Usuario getInstance() {
        return ourInstance;
    }

    public String getname() {
        return nombre;
    }

    public String getPassword() {
        return password;
    }

    private User() {

    }
}

How can i save all the information in the different singleton classes? When i do this:

String a = User.getInstance().name;

It said that is empty.

Thank you very much.

PD: if any moderator can put the code more visual will be so nice, because i'm new and i don't find anything. Thank you.

because the name is empty, put the class when you parse the json data — diegoveloper, Nov 22 '17 at 16:12

Look at this answer

What you have to do is convert the string into a json array and then with a for loop iterate and the logic in each iteration.

I get lost in the loop – David_helo Nov 22 '17 at 16:56
in each iteration of the for loop, do the logic you want. – exe Nov 23 '17 at 14:03
