your if block needs modified in order make work:

        if(e.getsource()==button1) {             obj[t].name=textfield.gettext();             t++;              //what code should come here reuse same panel again???              textfield.settext(""); // clears textfield re-use          } else if(e.getsource()==button2){                 system.exit(0);         } 

hope helps
