如何解决Exhausted ResultSet问题？

Question

我正在使用JAVA与Oracle 10g合作，我试图计算出以下代码，但它继续显示＆＃34; Exhausted Resultset＆＃34; ..有谁知道我怎样才能获得正确的输出？任何与此相关的帮助将不胜感激......

ResultSet rs = stmt.executeQuery("select * from ATTENDANTS");
ResultSet rs2 = stmt.executeQuery("select * from ATTENDANCE"); 
String insert = ("INSERT INTO ATTENDANTS ( Attendant_Name, Attendant_Age, Attendant_Contact_No, Attendant_Department_Name, REGISTRATION_NUM) VALUES('" + naam + "','" + umar + "','" + number + "', '" + deprt + "' , '" + registration + "')");
String insert2 = ("INSERT INTO ATTENDANCE ( Attendant_Name, Attendant_Age, Attendant_Contact_No, Attendant_Department_Name, REGISTRATION_NUM) VALUES('" + naam + "','" + umar + "','" + number + "', '" + deprt + "' , '" + registration + "')");
//ResultSetMetaData rsmd = rs.getMetaData();
//boolean colname = rsmd.equals(rs.getString(1));
while(rs.next() || rs2.next()){
   int a = naam.compareTo(rs.getString(1));
   int b = naam.compareTo(rs2.getString(1));
   int c = registration.compareTo(rs.getString(5));
   int d = registration.compareTo(rs2.getString(7));
        if((naam.equals(rs.getString(1)) && name.equals(rs2.getString(1))) || (registration.equals(rs.getString(5)) && registration.equals(rs2.getString(7)))){
            System.out.println("Record Already Exist");
            JOptionPane.showMessageDialog(null, "Name already exists in Record");
            //faceFrame.repaint();
            System.out.println("Already EXISTS");
        }
        //else if((a == 0 && c == 0) || (b == 0 && d == 0)){
        if((a == 0 && c == 0) || (b == 0 && d == 0)){
            stmt.executeQuery(insert);
            stmt.executeQuery(insert2);
            System.out.println("INSERTION DONE");
        }
       //else
       //System.out.println("Insertion Unsuccessfull");
    }
}
