Write your own JSON parser that doesn't rely on reflection

How do you  write json parser without reflection, create new java calls for each json data class structure?

How do you  write json parser without reflection, create new java calls for each json data class structure?

Parsing without reflection means you have to know the structure of the JSON. All you have to do if read the document and interpret it as fields and values

 

{ "item": { "name":"Cannonball", "id":2, "price":340 } }

 

translates into

public class Item {

    private String name;
    private Integer id;
    private Integer price;

}

So you can read the page into a string, get rid of "item":  { } and " ", split by , and you will have field:value pairs which you can insert into your Item instances
