2、編寫異常類TeamException

用于封裝整個項目中的異常,例如

添加員工到開發(fā)團隊時會遇到如下失敗情況

例如從團隊中刪除員工會遇到如下失敗情況

  • 找不到該成員,無法刪除

package com.atguigu.service;

 

public class TeamException extends Exception {

 

??? public TeamException() {

??? super();

??? }

 

??? public TeamException(String message) {

??????? super(message);

??? }

}

 

3、編寫業(yè)務類NameListService

service模塊為實體對象(Employee及其子類如程序員等)的管理模塊, NameListService和TeamService類分別用各自的數(shù)組來管理公司員工和開發(fā)團隊成員對象

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");

??? }

}
