JAVA入门学习-学习如何自定义一个实体类，用于存储一组数据。

实体类：由下大致理解为：因为万物皆对象，所以我们可以把一个实体或一个事物抽象成类，就成了实体类。

然后因为我们数据都是存在数据库中，所以通过实体类，建立数据层和逻辑层的联系。

引用一下别人在实体类的经验

一、实体类的名字尽量和数据库的表的名字对应相同。

二、实体类应该实现java.io.Serializable接口。

三、实体类应该有个无参的构造方法。

四、实体类应该有个有参（所有的参数）的构造方法。

五、实体类有属性和方法，属性对应数据库中表的字段，方法主要有getter和setter方法。

六、实体类还应该有个属性serialVersionUID。

例如：private static final long serialVersionUID = -6125297654796395674L;

七、属性一般是private类型，方法为public类型，对于数据库自动生成的ID字段对应的属性的set方法为private。

话不多说，实践见真知：

目标就建立一个会诊的实体类，再存储一组会诊数据。
