Answer 1

you have to set the border for ur component, u can not call set border on the air..........
i have changed your code like this
     year_panel.setBorder(BorderFactory.createCompoundBorder(BorderFactory.createTitledBorder(title),BorderFactory.createEmptyBorder(5,5,5,5)));
and
                              public JPanel date_panel,year_panel, month_panel,day_panel;
instead of private i have used public.It is compiling.
