The Date object works, but much better to use Calendar.
Calendar cal = Calendar.getInstance();
cal.setTime(milliseconds);
SimpleDateFormat sdf = new SimpleDateFormat("MM/dd/yyyy"); // see
javadocs for how to construct date strings.
sdf.format(cal.getTime());
Sometimes I construct my human readable strings in a separate function
by myself, mostly because I imagine it's faster. Something like.
int iMonth = cal.get(Calendar.MONTH) + 1; // Months from the calendar
are offset by one. Add one if you want human readable.
int iDay = cal.get(Calendar.DAY_OF_MONTH);
String month = Integer.toString(iMonth);
if(iMonth < 10){
month = "0" + month; // Otherwise, you might get something like
1/1/1900, instead of 01/01/1900
}
String day = Integer.toString(iDay);
if(iDay < 10){
day = "0" + day;
}
String humanReadable = month + "/" + day + "/" cal.get(Calendar.YEAR);
But really, you should be using SimpleDateFormat, I suppose...
