月の最初の日を選択する場合例：- 2014 年 4 月 1 日、
それは次のように表示されます：jdatechooserで91-04-2014、私のdateFormatStringは：「dd-mm-yyyy」です
これが私のコードです:

this.setIconImage(ic.getImage());
//initializations
stud.clearSelection();
gradeText = ((JSpinner.DefaultEditor) grd.getEditor()).getTextField();
dob.setDateFormatString("DD-MM-YYYY");
}
public final void KeyTypos() {
