java面向对象程序设计通过继承 Exception 或 RuntimeException 类来创建自定义异常，满足特定业务需求。// 自定义用户不存在异常// 自定义密码错误异常if (!// 抛出用户不存在异常throw new UserNotFoundException("用户不存在");if (!// 抛出密码错误异常throw new PasswordWrongException("密码错误");System.out.println("登录成功");try {// 调用登录方法，可能抛出异常。阅读详情

（1）定义一个快递员类DeliveryMan，包括姓名、电话和配送区域三个数据成员，其他set/get方法和构造方法。（2）定义一个测试类Client，创建一个快递员的数组，用直接赋值的形式保存不少于5个的快递员信息（数据自拟，地域要求查找地图保证真实）。在控制台输入快递地址，为其匹配相应的快递员，输出其姓名和联系方式；无法匹配时给出提示。可多次查询，输入quit后结束查询。运行效果如下：请输入您要配送的地址：学院路为您服务的快递员是：De 联系电话：1661056879 请输入您要配送的地址：天乐园抱歉，没有找到为您配送的快递员请输入您要配送的地址：荷清路为您服务的快递员是：James 联系电话：1669871236 请输入您要配送的地址：quit 再见

		DeliveryMan deliveryMan1 = new DeliveryMan("De", "1661056879", "学院路");
		DeliveryMan deliveryMan2 = new DeliveryMan("", "", "天乐园");
		DeliveryMan deliveryMan3 = new DeliveryMan("James", "1669871236", "荷清路");
