Question

what is an efficient way to get a certain time for the next day in Java? Let’s say I want the long for tomorrow 03:30:00. Setting Calendar fields and Date formatting are obvious. Better or smarter ideas, thanks for sharing them!

I take the brute force approach

// make it now Calendar dateCal = Calendar.getInstance(); // make it tomorrow dateCal.add(Calendar.DAY_OF_YEAR, 1); // Now set it to the time you want dateCal.set(Calendar.HOUR_OF_DAY, hours); dateCal.set(Calendar.MINUTE, minutes); dateCal.set(Calendar.SECOND, seconds); dateCal.set(Calendar.MILLISECOND, 0); return dateCal.getTime();
