SimpleDateFormat sdf = new SimpleDateFormat("yyyy/MM/dd");
        Locale locale = new Locale("ja", "JP", "JP");//locale for Japanese
        Calendar cal = Calendar.getInstance(locale);  //japanese calender object
        DateFormat df = DateFormat.getDateInstance(DateFormat.LONG,locale);
        try{
        Date date = sdf.parse("1930/09/27");
            System.out.println(df.format(date));
        }catch(Exception e){
            System.out.println(e.getMessage());
        }

Hi,
If I give the Input date 1930/10/27 (in english), then program must display the date as S5.10.27 (it's japanese date with 'S' indicating ERA)
But this will happpen only when i run the program in JDK 6.0.
In JDK 1.5, for the above input, the output is 1930/10/27 (which is wrong)
Still I don't have compilation and running problems in both. Can anybody expalin why it is so?
I think i tried my best to restate the question.
Thanx
Aris
