dcyh.java~10~

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,rs3,rs4;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");
             rs3=stmt.executeQuery("select * from yhxx");
            rs4=stmt.executeQuery("select * from sttk");
