problem in deleting data

[harsimran05]

when i click on delete button following exception is generated
java.lang.ClassCastException: java.lang.String cannot be cast to java.lang.Integer
at MyFrame.actionPerformed(AcctHld.java:226)

code of my delete button is

if(o.equals(bDelete)){   
                try {   
                 int accountno=(Integer)mAccthld.getValueAt(tAcctHld.getSelectedRow(),0);   
                    mAccthld.removeRow(tAcctHld.getSelectedRow());   
                       
                        Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");   
     Connection con=DriverManager.getConnection("jdbc:odbc:DRIVER=Microsoft Access DRIVER (*.mdb);DBQ=fddata.mdb");   
PreparedStatement ps=con.prepareStatement("delete from accthld where AccountNo=?");   
                        ps.setInt(1,accountno);   
                        int s=ps.executeUpdate();   
                        System.out.println(s);   
                        con.close();   
                }   
                catch(Exception ex){   
                    ex.printStackTrace();   
                }   
                            
                   
            }

and when i use integer.parseint instead of typecasting into integer then i get a error
symbol : method parseInt(java.lang.Object)
location: class java.lang.Integer
int accountno=(Integer.parseInt(mAccthld.getValueAt(tA cctHld.getSelectedRow(),0)));

I presume mAccthld is a JTable? Cast the returned value of getValueAt to a String, then use Integer.parseInt to get the int value.
