JOptionPane.showMessageDialog(this,
"Plase Enter Student lastName",
"Error",JOptionPane.INFORMATION_MESSAGE );

You need to test if getLast() return null :

if (getLast()!=null) /* close the dialog window */

1.) if (getLast()!=null) /* close the dialog window */
why should i close the dialog, the JOptionPane dialog is opened only when getLast() == null or Not, --- i think so.

2.) if(last == null || last == "")
do u think i should check for empty string ( last == "")
