推荐答案

您正尝试访问null对象的属性.
尝试通过源代码进行调试，以自行解决问题.长期来看会对您有帮助.

You are trying to access an attribute for an object that is null.
Try debugging through your source code to figure the problem by yourself. It will help you in the longer term.

您好，

也许您忘了创建该类的实例?

Hi,

Maybe you forgot to create an instance of that class?

Loan loan = new Loan();

在给定代码之前添加该代码可能会有所帮助！

问候，
爱德华

Adding that before the given code might help!
