public class BaseDao {

             // Create and execute an SQL statement that returns some data.    
           String SQL = "SELECT * FROM newu_log_alarm";    
           stmt = con.createStatement();    
           rs = stmt.executeQuery(SQL);    
    
          // Iterate through the data in the result set and display it.    
            while (rs.next()) {    
                 System.out.println(rs.getString(1) + " " + rs.getString(2)+" " + rs.getString(3)+" " + rs.getString(4)+" " + rs.getString(5)+" " + rs.getString(6)+" " + rs.getString(7)+" " + rs.getString(8)+" " + rs.getString(9)+" " + rs.getString(10)+" " + rs.getString(11)+" " + rs.getString(12)+" " + rs.getString(13)+" " + rs.getString(14));    
                }    
         }    
         // Handle any errors that may have occurred.    
         catch (Exception e) {    
            e.printStackTrace();    
         }    
              finally {    
            if (rs != null)    
                 try {    
                    rs.close();    
                 } catch (Exception e) {    
                 }    
             if (stmt != null)    
                 try {    
                     stmt.close();    
                 } catch (Exception e) {                   
                  
                 }    
             if (con != null)    
                 try {    
                     con.close();    
                 } catch (Exception e) {    
                 }           
             }    
     }
}各位我想问问如果我想在main方法之外在加两个方法public ResultSet getResultSet(String sql1, Object[] params, int pageNow)

和public boolean modify(String sql, Object[] params)

那该怎么做了,谢谢各位师哥,师姐了

写成员方法,把需要的部分抽取出来,你要理解面向对象,这个应该很容易的
