Java MS Access的Jdbc Odbc连接问题

我想用MS Access创建一个Jdbc Odbc连接。我创建了一个Ms Access文件，Jdbc Odbc连接名为Student\u test

所以我在这里分享了一张照片，在那里有人可以找到连接的名称

代码块：

import java.sql.*;
public class Connection_sample{
public static void main(String[] args) {
    try{
        Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
        Connection con = DriverManager.getConnection("jdbc:odbc:Student_test","","");
        Statement s= con.createStatement();
        s.executeQuery("select * from Student");
        ResultSet rset = s.getResultSet();
        while(rset.next()){
            System.out.println(rset.getString("ProductName"));
        }
    } catch (ClassNotFoundException | SQLException e) {
        e.printStackTrace();
    }

}

}

我正在使用JDK 8和Intellij Idea。之前我使用的是JDK13，出现了一些错误。在网上搜索之后，我知道JDK 8适合数据库连接。所以我安装了它并通过JDK 8运行

现在，如果我尝试从IntelliJ idea运行它，就会出现这些错误

如果我试图从终端运行它，就会出现这些错误

修复这些错误的任何帮助都是值得注意的

提前感谢。

第一个问题是驱动程序类未加载。第二个错误是版本不匹配，比如说您在更高版本上编译，并试图在更低的java版本上运行。为了解决第一个问题，您需要一个此处所述的驱动程序；第二个问题，您需要使用相同（或更低）版本进行编译。第一个问题与JdbcOdbcDriver自Java 8以来不再可用这一事实有关。
