JavaSE进阶
2、编写异常类TeamException
用于封装整个项目中的异常，例如
添加员工到开发团队时会遇到如下失败情况
例如从团队中删除员工会遇到如下失败情况
- 找不到该成员，无法删除
|
package com.atguigu.service;
public class TeamException extends Exception {
public TeamException() { super(); }
public TeamException(String message) { super(message); } }
|
3、编写业务类NameListService
service模块为实体对象（Employee及其子类如程序员等）的管理模块， NameListService和TeamService类分别用各自的数组来管理公司员工和开发团队成员对象
|
package com.atguigu.service;
import com.atguigu.bean.Employee;
public class NameListService { private Employee[] employees;
public Employee[] getAllEmployees() { return employees; }
public Employee getEmployee(int id) throws TeamException { for (Employee e : employees) { if (e.getId() == id) return e; } throw new TeamException("该员工不存在"); } }
