Java Program to return a Date set to the first possible millisecond of the day after midnight
Let us first set the calendar object.
Calendar calendar = Calendar.getInstance();
Use the getMinimum() method in Java to return the minimum value for the given calendar field. We will use it to set the minute, hours second and milliseconds.
For hour and minute.
calendar.set(Calendar.HOUR_OF_DAY, calendar.getMinimum(Calendar.HOUR_OF_DAY)); calendar.set(Calendar.MINUTE, calendar.getMinimum(Calendar.MINUTE));
For second and milliseconds.
// second calendar.set(Calendar.SECOND, calendar.getMinimum(Calendar.SECOND)); // millisecond calendar.set(Calendar.MILLISECOND, calendar.getMinimum(Calendar.MILLISECOND));
The following is an example that returns a Date set to the first possible millisecond of the day after midnight.
Example
import java.util.Calendar;
import java.util.GregorianCalendar;
public class Demo {
public static void main(String[] argv) throws Exception {
Calendar calendar = Calendar.getInstance();
// hour and minute
calendar.set(Calendar.HOUR_OF_DAY, calendar.getMinimum(Calendar.HOUR_OF_DAY));
calendar.set(Calendar.MINUTE, calendar.getMinimum(Calendar.MINUTE));
// second
calendar.set(Calendar.SECOND, calendar.getMinimum(Calendar.SECOND));
// millisecond
calendar.set(Calendar.MILLISECOND, calendar.getMinimum(Calendar.MILLISECOND));
System.out.println(calendar.getTime());
}
}Output
