json针对list map set 应用

package JSONtest;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.HashSet;
import java.util.List;
import java.util.Map;
import java.util.Set;

import net.sf.json.JSONObject;

public class Jsontest1 {
public static void main(String args[]){
//生成一个JSONObject对象
String data = "{}";
JSONObject jsonObj = JSONObject.fromObject(data);

//1.put 基本类型值
int i=0;
for(i=0; i<5; i++){
jsonObj.put("id"+i, i);
}
System.out.println(jsonObj.toString());

//2.put 一个JSONObject对象
JSONObject obj1 = JSONObject.fromObject(data);
for(i=0; i<5; i++){
obj1.put("child"+i, i);
}
jsonObj.put("JSONObject", obj1);
System.out.println(jsonObj.toString());

//3.put 数组
String[] strArr = new String[]{"加","数","组"};
jsonObj.put("arr", strArr);
System.out.println(jsonObj.toString());

// 4.put List
List<String> list = new ArrayList<String>();
list.add("加");
list.add("列");
list.add("表");
jsonObj.put("list", list);
System.out.println(jsonObj.toString());

//5.put Set
Set<String> set = new HashSet<String>();
set.add("加");
set.add("集");
set.add("合");
jsonObj.put("set", set);
System.out.println(jsonObj.toString());

//6.put Map
Map<String,Object> map = new HashMap<String, Object>();
map.put("map1", "加");
map.put("map2", "映");
map.put("map3", "射");
jsonObj.put("map", map);
System.out.println(jsonObj.toString());

//7.putAll Map
jsonObj.putAll(map);
System.out.println(jsonObj.toString());

//8.组合: (返回的结果value是一个对象数组)
List<JSONObject> jlist = new ArrayList<JSONObject>();
JSONObject j = null;
for(i=0; i<3; i++){
j = JSONObject.fromObject(data);
j.put("aaaa"+i, i);
j.put("bbbb"+i, i);
j.put("cccc"+i, i);
jlist.add(j);
}
jsonObj.put("succList", jlist);
System.out.println(jsonObj.toString());

//9.组合 : (返回的结果value是一个对象数组，对象的某个属性又是一个对象(嵌套))
List<JSONObject> jlist1 = new ArrayList<JSONObject>();
for(i=0; i<3; i++){
j = JSONObject.fromObject(data);
j.put("xxxx"+i, i);
j.put("yyyy"+i, i);
j.put("zzzz"+i, obj1);
jlist1.add(j);
}
jsonObj.put("failList", jlist1);
System.out.println(jsonObj.toString());

//10.组合: 可以任意嵌套
JSONObject superJson = JSONObject.fromObject(data);
superJson.put("super", jsonObj);
superJson.put("base", "base");
System.out.println(superJson.toString());
}
}

输出结果：
