第一种方法:

 String str = "{\'array\':[{\'id\':5,\'name\':\'张三\'},{\'id\':6,\'name\':\'李四\'}]}";
 JSONArray jsonArray = null;
 jsonArray = jsonobj.getJSONArray("array");//获取数组
 System.out.println(jsonArray.getJSONObject(0).get("name"));

String str = "[{\'columnId\':5,\'columnName\':\'人文历史\'},{\'columnId\':2,\'columnName\':\'商业视野\'}]}";
JSONArray jsonArray = null;
jsonArray = new JSONArray(str);
System.out.println(jsonArray.getJSONObject(0).get("columnName"));

第二种方法:

 JSONObject json1=JSONObject.fromObject("{\'username\' : \'11111\',\'clientid\' : \'\',\'password\' : \'222222\'}");  
Map<String, Object> map =json1;  
for (Entry<String, Object> entry : map.entrySet()) {  
     System.out.println(entry.getKey()+"="+entry.getValue());  
 }
