How to determine tomorrow's date in J2ME for use in a DateField?

问题

I basically want to be able to show tomorrows date

I have this which shows today date

private Date date = new Date();

i tried this but this gave me jan 1 1970

private Date date = new Date(+1);

please help

回答1:

The integer (actually long) parameter for the Date constructor is for specifying the milliseconds of offset from January 1st, 1970, GMT.

You need to use a Calendar instead

Calendar cal = Calendar.getInstance();
cal.add(Calendar.DATE, 1);
Date date = cal.getTime();

回答2:

Note, the Date.setBlah and Date.getBlah methods are deprecated, Calendar should be used instead. (Not sure if that's available in J2ME though.)

private Date date = new Date();
date.setDate(date.getDate() + 1);

回答3:

As suggested here, use an implementation of class Calendar like thus:

Calendar myCalendar = Calendar.getInstance();
long tomorrow = myCalendar.getTimeInMillis() + 24 * 60 * 60 * 1000;
myCalendar.setTimeInMillis(tomorrow);

And do whatever you want with that...

Hope this helps,
