说明：

因为上个代码，总是要输入完整的绝对路径，比较麻烦，于是，就写了这个小程序，直接进入文件对话框选择需要运行的class文件。

只需要提前输入完整的类名。

注意：加的MyTest必须打个包，加上：
import cn.hncu.myJuniitApp.vo.MyTest;
不然不是同一个注解呢。

测试的类：

也许有人认为一个类完全就可以解决这个问题了，你还写这么多的包，这么多类，这不是麻烦嘛。
我想说，虽然麻烦，但是可以让我们看起来结构清楚，谁调用谁也很明白，而且是面向接口编程。
这个写得更加规范，特别是以后到公司工作，基本上都是几个人开发同一个项目的，这个人写这里的，那个人写那里的，如果没有规范，怎么行呢。怎么合作开发同一个项目呢。

所以，分包是必须的。分逻辑层和数据层也是需要的。特别是一个层的铁三角，必须都要有。
接口，工厂方法，实现类，缺一不可！！！
