dcyh.java~4~

提供了一种注册机算法的实现. 里面共有两份分别是题库的代码和注册机的代码

package dcwork;

import java.sql.*;

public class Dcyh {
  String name;
   ResultSet rs,rs2;Connection con;Statement stmt;
   public  Dcyh(){
     connection();
  }
  public void connection()
{
   try{Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
}
   catch(ClassNotFoundException e){}
       try
   {
     con = DriverManager.getConnection("jdbc:odbc:DCDB", "", "");
             stmt = con.createStatement();
               rs=stmt.executeQuery("select * from yhxx");
            rs2=stmt.executeQuery("select * from sttk");


               //while(rs.next())
                // name=rs.getString(1);
                 //System.out.println(name);
     }catch(SQLException e)
     {
       System.err.println(e);
     }
     }
}
