Java之从零开始制作火车售票系统（一）

Java之从零开始制作火车售票系统

首先建立数据库，方便能够存储数据

package We;

import java.sql.Statement;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;

public class TrainDatabase {
    Connection conn = null;
    String url = "jdbc:derby:TrainDB;create=true";  //url of the DB host
    //jdbc:derby://localhost:1527/TrainDB
    String username = "pdc";  //your DB username
    String password = "pdc";   //your DB password
    Statement statement;
    ResultSet rs;
    
       public void autoConnectTrainDB() {
        try {

            conn = DriverManager.getConnection(url, username, password);
            statement = conn.createStatement();
            statement.executeUpdate("CREATE TABLE TRAIN (STARTPOINT VARCHAR(50), ENDPOINT VARCHAR(50), SEATTYPE VARCHAR(50), NAME VARCHAR(50),SEX VARCHAR(50),TELE FLOAT)"); //Create BOOK table
            statement.executeUpdate("INSERT INTO TRAIN VALUES ('SHANG HAI', 'ZHE JIANG', 'Second Seat', 'MIKE','MALE',18036554221) ");
        } catch (Throwable ex) {
            System.err.println("SQL Exception: " + ex.getMessage());
        }
    }

    /**
     * @param args the command line arguments
     */
    
}

然后主方法能够运行数据库

package We;
import java.sql.ResultSet;
/**
 *
 * @author shaojiangteng
 */
public class TrainDatabasetest {

    public static void main(String[] args) {
        TrainDatabase train=new TrainDatabase();
        train.autoConnectTrainDB();
   
    }
}
