实施旅行社的菜单驱动程序
先决条件： Java中的类和对象， Java中的 Switch Case 语句
问题陈述：
编写一个程序，使用Java 8、MYSQL 数据库和 JDBC 构建一个简单的公交出行服务应用程序，可以执行以下操作：
- 通过各种付款方式为给定路线上的用户/乘客预订车票。
- 使用客票详细信息和用户凭据取消用户/乘客预订的客票
- 通过工单详细信息和用户凭据打印工单。
- 通过已注册的票证 ID 或电子邮件 ID 和用户凭据更新预订机票上的乘客详细信息。
方法：最初，我们需要建立一个数据库来存储公交车的信息和预订信息。这里使用了 MySQL 数据库。最初，我们需要设置数据库。因此，按照以下步骤设置数据库：
- 最初，使用工作台在 MySQL 数据库中创建一个数据库。
- 创建数据库后，会创建多个表，表示多个旅行服务，其中每个表都包含乘客的详细信息。这些表是通过以下方式创建的：
- 现在，由于每个表都必须包含乘客的详细信息，因此每个表都具有以下属性：
现在，我们需要在上面创建的数据库和Java程序之间建立一个连接。为此，请遵循以下步骤：
- 最初，我们需要在我们将开发应用程序的类中收集数据库和驱动程序信息。这样做的语法是：
String driverClassName = “com.mysql.jdbc.Driver”;
String url=”jdbc:mysql://localhost/jdbc”;
String user=”root”;// The default password is root.
// But we can set up any password
// for MYSQL database
String pwd= “root”; - 现在，我们需要加载 JDBC 驱动程序。这是通过以下语句执行的：
// Class.forName method returns the
// Class object associated with the
// class or the interface
Class.forName(driverClassName).newInstance(); - 初始化数据库后，我们需要连接到它。所以，我们需要创建一个连接。连接创建为：
Connection con = DriverManager.getConnection(url, user, pwd);
System.out.println(“con—->”+con); - 连接后，我们应该能够执行 SQL 语句以获取数据或更新数据或将其发布到数据库中。为了执行语句，使用以下语法：
Statement st = con.createStatement();
// Creating SQL query
String sql= “” ;// Executing the query
st.executeUpdate(sql); - 最后，完成执行后，我们需要关闭连接。与数据库的连接关闭为：
st.close();
con.close();
至此，我们已经初始化了数据库，并在数据库和Java程序之间建立了连接。现在，我们需要根据功能定义所有方法。程序中的方法如下：
- 订票：要订票，我们首先需要选择路线。该选项被给予用户在一组预定义的路线中选择一条路线。对于所有路线，用户必须输入他的详细信息，例如姓名、年龄、手机号码、电子邮件等。现在，用户将获得特定路线中可用旅行的列表。根据用户的选择，数据存储在上面创建的数据库的相应表中。为了做到这一点，在每个案例都是旅行提供商的选择的情况下使用 switch-case。
- 取消车票：与上述方法类似，我们需要实现取消功能，用户可以取消预订的车票。为此，我们需要首先获取需要取消门票的用户的详细信息，并使用输入期间提供的用户的手机号码和电子邮件 ID 进行验证。
- Print Ticket：现在，实现了打印函数。为了打印车票，需要获取用户详细信息，例如已预订车票的公共汽车，并以电子邮件 ID 作为输入以查找车票详细信息并打印详细信息。
- 更新票：为了更新票，用户必须首先有一个预订票。因此，将用户的电子邮件 ID 作为输入来验证票证是否存在。获取email id后，在数据库中进行搜索操作，搜索ticket，然后将更新后的新详情作为输入，在数据库中进行更新。
以下是上述功能的完整实现以及数据库连接：
