JavaSE進(jìn)階
2、編寫(xiě)異常類(lèi)TeamException
用于封裝整個(gè)項(xiàng)目中的異常，例如
添加員工到開(kāi)發(fā)團(tuán)隊(duì)時(shí)會(huì)遇到如下失敗情況
例如從團(tuán)隊(duì)中刪除員工會(huì)遇到如下失敗情況
- 找不到該成員，無(wú)法刪除
|
package com.atguigu.service;
public class TeamException extends Exception {
??? public TeamException() { ??? super(); ??? }
??? public TeamException(String message) { ??????? super(message); ??? } }
|
3、編寫(xiě)業(yè)務(wù)類(lèi)NameListService
service模塊為實(shí)體對(duì)象（Employee及其子類(lèi)如程序員等）的管理模塊， NameListService和TeamService類(lèi)分別用各自的數(shù)組來(lái)管理公司員工和開(kāi)發(fā)團(tuán)隊(duì)成員對(duì)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("該員工不存在"); ??? } }
