我有两个类，类Event和类HazardSubmission，它们扩展了类Event。
班级Event有一个属性dateCreated，getDateCreated()和setDateCreated(String);
当我尝试：
HazardSubmission hs = new HazardSubmission();
hs.setDateCreated("A");
我假设它会调用类Event中的setter，但是它在类HazardSubmissio n中寻找setter！
这是错误，非常感谢一些帮助！ ：）

答案 0 :(得分：2)
根据您的XML创建的日期应该是一个时间戳，但看起来您已将该属性声明为String。
您可以更改其中一种类型以便匹配吗？
