Question

感谢我的项目出现问题之前，我的项目是在Android中制作应用程序然后应用程序可以连接到我公司的数据库，但这不是连接

import java.sql.DriverManager;
import java.sql.SQLException;
import java.util.logging.Level;
import java.util.logging.Logger;

     public class ConnectedAccessActivity {
 Connection conn;
 String url="jdbc:odbc:JavaMsAccess";
 String user="";
 String pass="";
 public Connection getConnection(){
 try {
 Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
 conn=DriverManager.getConnection(url,user,pass);
 System.out.println("Connected!!!");
 } catch (SQLException ex) {
 Logger.getLogger(ConnectedAccessActivity.class.getName()).log(Level.SEVERE, null, ex);
 } catch (ClassNotFoundException ex) {
 Logger.getLogger(ConnectedAccessActivity.class.getName()).log(Level.SEVERE, null, ex);
 }
 return conn;
 }
 public static void main(String [] args){
 ConnectedAccessActivity acc=new ConnectedAccessActivity();
 acc.getConnection();
 }

}

它是eclipse中的控制台

代码看起来只是一个普通的Java程序。您应该从中删除Android库，以便能够以Java格式运行它。
