        JSONArray ja = new JSONArray();
        ja.put("11");
        ja.put("22");
        ja.put("33");
        
        JSONArray ja2 = new JSONArray();
        ja2.put("aa");
        ja2.put("bb");
        
        ja.put(ja2);
        
        System.out.println(ja.toString());
//	jsonarray	这个代表集合  左右两边[]        
//				["11","22","33",["aa","bb"]]

        JSONObject jsonObject = new JSONObject();
        
        try {
        	
			jsonObject.put("aaa", "111");
	        jsonObject.put("bbb", "222");
	        jsonObject.put("ccc", "333");
	        jsonObject.put("ddd", "444");
	        
		} catch (JSONException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
        
        System.out.println(jsonObject.toString());
//		jsonObject就是中间有个:号,然后左右两边是{}
//      {"ddd":"444","ccc":"333","bbb":"222","aaa":"111"}
