Get yesterday's date using Date

What is an elegant way set to a Java Date object’s value to yesterday?

Answer 1

Do you mean to go back 24 hours in time.

 Date date = new Date(System.currentTimeMillis() - 24 * 60 * 60 * 1000L);

or to go back one day at the time same time (this can be 23 or 25 hours depending on daylight savings)

 Calendar cal = Calendar.getInstance();
 cal.add(Calendar.DATE, -1); 

These are not exactly the same due to daylight saving.
