Parsing JSON data from text file

[admin]

Hi I have Java class which will read &amp;parse the JSON data from file and insert into DB,they are storing NAME,AGE and PHONE. The program is working fine;But my requirement is ,I have a different JSON data which needs to do same operation,I want to store <strong>AGE</strong>,<strong>ID</strong> and <strong>TYPE</strong>.I have mentioned my JSON data in the last part

I got this code from the <a href="https://javapages4all.wordpress.com/2012/12/10/read-from-json-file-and-persist-into-mysql/" rel="nofollow">https://javapages4all.wordpress.com/2012/12/10/read-from-json-file-and-persist-into-mysql/</a>

test.json:

{'profiles':[
{'name':'Girish', 'age': 44, 'phone':'203-203-2030'},
{'name':'Alex','age':31, 'phone':'203-203-2030'},
{'name':'Amy', 'age': 24, 'phone':'203-203-2030'},
{'name':'Melissa','age':21, 'phone':'203-203-2030'}
]
}

Java Class:

        int count = 0;
        Iterator<Object> iterator = nameArray.iterator();

        while (iterator.hasNext()) {

    }

    private static Connection getConnection() {
        Connection con = null;
        String url = "jdbc:mysql://localhost:3306/";
        String db = "jsondata";

        String user = "root";
        String pass = "root";
        try {
            Class.forName(driver);
            con = DriverManager.getConnection(url + db, user, pass);
        } catch (ClassNotFoundException e) {
            e.printStackTrace();
        } catch (SQLException e) {
            e.printStackTrace();
        }
        return con;
    }
}

My JSON:

[{"emp":{"age":34,"ID":3423423},"type":"s"}, 
{"emp":{"age":43,"ID":324324235},"type":"s"}, 
{"emp":{"age":36,"ID":324324236},"type":"v"},
{"emp":{"age":46,"ID":324324238},"type":"s"},
{"emp":{"age":55,"ID":324324243},"type":"s"},
{"emp":{"age":44,"ID":324324287},"type":"s"}]

for the above program i want to use this JSON data
