//在www.json.org上公布了很多Java下的json解析工具，其中org.json和json-lib比较简单，两者使用上差不多。下面两段源代码是分别使用这两个工具解析和构造//JSON的演示程序。   
//这是使用json-lib的程序：   
import java.util.HashMap;   
import java.util.Map;   
  
import net.sf.json.JSONObject;   
  
public class Test {   
  
    public static void main(String[] args) {   
        String json = "{\"name\":\"reiz\"}";   
        JSONObject jsonObj = JSONObject.fromObject(json);   
        String name = jsonObj.getString("name");   
        
        jsonObj.put("initial", name.substring(0, 1).toUpperCase());   
  
        String[] likes = new String[] { "JavaScript", "Skiing", "Apple Pie" };   
        jsonObj.put("likes", likes);   
  
        Map <String, String> ingredients = new HashMap <String, String>();   
        ingredients.put("apples", "3kg");   
        ingredients.put("sugar", "1kg");   
        ingredients.put("pastry", "2.4kg");   
        ingredients.put("bestEaten", "outdoors");   
        jsonObj.put("ingredients",ingredients);   
        
        System.out.println(jsonObj);   
    }   
}   
//这是使用org.json的程序：   
import java.util.HashMap;   
import java.util.Map;   
  
import org.json.JSONException;   
import org.json.JSONObject;   
  
public class Test {   
  
    public static void main(String[] args) throws JSONException {   
        String json = "{\"name\":\"reiz\"}";   
        JSONObject jsonObj = new JSONObject(json);   
        String name = jsonObj.getString("name");   
  
        jsonObj.put("initial", name.substring(0, 1).toUpperCase());   
  
        String[] likes = new String[] { "JavaScript", "Skiing", "Apple Pie" };   
        jsonObj.put("likes", likes);   
  
        Map <String, String> ingredients = new HashMap <String, String>();   
        ingredients.put("apples", "3kg");   
        ingredients.put("sugar", "1kg");   
        ingredients.put("pastry", "2.4kg");   
        ingredients.put("bestEaten", "outdoors");   
        jsonObj.put("ingredients", ingredients);   
        System.out.println(jsonObj);   
  
         
    }   
}
