我正在尝试连接我正在制作的关于我在 MS Access 中创建的大学数据库的 java 程序。

我的代码是这样的:

    package Uni;
    import java.util.*;
    import java.sql.*;

    public class College {
        static final String database_URL = "H:/CSCI 213/Labs/Lab 11 - 12/src/Uni/Uni.accdb";
        static Scanner input = new Scanner(System.in);
        static Scanner in = new Scanner(System.in);

        @SuppressWarnings("unused")
        public static void main(String[] args) {
            Connection connection = null;
            Statement statement = null;
            ResultSet resultset = null;
            String name;
            int age;
            int id;
            String choice = "y";

            while(choice.equalsIgnoreCase("y")) {
        System.out.println("What Would you like to do");
        System.out.println("1- Insert");
        System.out.println("2- Update");
        System.out.println("3- Search");
        System.out.println("4- Delete");
        System.out.println("5- Exit");

        int x = input.nextInt();
        try {
                    connection = DriverManager.getConnection(database_URL);
                    //connection.commit();
                    //statement = connection.createStatement();
                    switch(x) {
                      case 1:   
                        System.out.println("Enter the name:");
                        name = input.nextLine();
                        System.out.println("Enter the Age:");
                        age = input.nextInt();
                        //statement.executeQuery("INSERT INTO Database VALUES ('"+name+"','"+age+"')");
                        Statement sta1 = connection.createStatement(); 
                        sta1.executeQuery("INSERT INTO Database VALUES ('"+name+"','"+age+"')");
                        sta1.close();
                        System.out.println("Your ID is: ");
                        //statement.executeQuery("select ID from Database where Name='"+name+"';");
                        Statement sta2 = connection.createStatement();
                        sta2.executeQuery("select ID from Database where Name='"+name+"';");
                        connection.commit();
                        sta2.close();
                        break;

                        case 2:
                        System.out.println("Enter the id of the person you'd like to update:");
                        id = input.nextInt();
                        System.out.println("Enter the name:");
                        name = input.nextLine();
                        System.out.println("Enter the Age:");
                        age = input.nextInt();
                        //statement.executeUpdate("UPDATE Database SET Age="+age+", Name='"+name+"' WHERE ID="+id+";");
                        Statement sta3 = connection.createStatement();
                        sta3.executeQuery("UPDATE Database SET Age="+age+", Name='"+name+"' WHERE ID="+id+";");
                        connection.commit();
                        sta3.close();
                        break;

                    case 3:
                        System.out.println("Enter the Name of the person you'd like to search for:");
                        name = input.nextLine();
                        //statement.executeQuery("select Name, Age from Database where Name='"+name+"';");
                        Statement sta4 = connection.createStatement();
                        sta4.executeQuery("select Name, Age from Database where Name='"+name+"';");
                        connection.commit();
                        sta4.close();
                        break;

                    case 4:
                        System.out.println("Enter the id of the person you'd like to delete:");
                        id = input.nextInt();
                        //statement.execute("DELETE FROM Database where ID='"+id+"';");
                        Statement sta5 = connection.createStatement();
                        sta5.executeQuery("DELETE FROM Database where ID='"+id+"';");
                        connection.commit();
                        sta5.close();
                        break;

                    case 5:
                        System.out.println("Terminating");
                        System.exit(0);

                    default:
                        System.out.println("Wrong Entry");
                    }

                }

           catch (SQLException e)  {
               System.out.println("SQLException: "+e.getMessage());
           }


           System.out.println("Would you like to try again ? (enter y for yes)");
           choice = in.nextLine();
           }
     }
   }

现在确切的输出如下

你想做什么 1- 插入 2- 更新 3- 搜索 4- 删除 5- 退出 1 SQLException: 没有找到适合 H:/CSCI 213/Labs/Lab 11 - 12/src/Uni/Uni.accdb 的驱动程序你想再试一次吗?(输入 y 表示是)

任何关于如何解决这个问题的想法都非常感谢

H:/CSCI 213/Labs/Lab 11 - 12/src/Uni/Uni.accdb是文件的路径,而不是有效的 JDBC URL。

您需要为特定数据库获取 JDBC 驱动程序 JAR 文件,在运行程序时将其放入类路径中,并使用正确的 JDBC URL。JDBC URL 的确切外观取决于您使用的数据库和驱动程序(查看文档)。

有关通过 JDBC 使用 Microsoft Access 数据库的信息,请参阅例如:如何将 Java 连接到 MS Access或搜索“Microsoft Access JDBC 驱动程序”。
