System.out.println(dep1.getDepartmentName()+"总共有"+dep1.getStaffNum()+"名员工");
System.out.println(dep2.getDepartmentName()+"总共有"+dep2.getStaffNum()+"名员工");
}
}
部门信息如下:
部门编号 部门名称 员工数组 员工人数
D001 人事部
D002 市场部
==========================
我这个写不出来，该怎么写啊。。

同学你好，同学代码完成的不错，测试类中可以按如下思路完成：
1、创建2个部门类对象，分别为市场部和人事部。创建3个职务类对象，分别为经理，助理，职员。
例如：
2、创建6个员工对象。调用员工的介绍方法，展示一下员工信息。
例如：
3、各个部门对象通过调用添加员工的方法，把对应的员工对象传递进去。
例如：
4、打印输出dep1和dep2的staffNum，展示一下员工数。
例如：
