Questo è il codice della jSpinner modificata per mettere interi..se a qualcuno dovesse servire

Calendar calendar = new GregorianCalendar();
int currentYear = calendar.get(Calendar.YEAR);
SpinnerModel jSpinner1Model = new SpinnerNumberModel(currentYear,currentYear - 100,currentYear + 100,1);
jSpinner1 = new JSpinner();
jPanel1.add(jSpinner1);
jSpinner1.setModel(jSpinner1Model);
jSpinner1.setEditor(new JSpinner.NumberEditor(jSpinner1, "#"));
jSpinner1.setBounds(441, 14, 98, 28);
jSpinner1.setBorder(new LineBorder(new java.awt.Color(0,0,0), 1, false));
jSpinner1.getEditor().setBorder(new LineBorder(new java.awt.Color(0,0,0),1,false));
jSpinner1.getEditor().setEnabled(false);
