Java Program to return a Date set to noon to the closest possible millisecond of the day

Java 8Object Oriented ProgrammingProgramming

Use the getMinimum() method in Java to returns the minimum value for the given calendar field. We will use it to set the minute, second and millisecond.

Let us first declare a calendar object.

Calendar dateNoon = Calendar.getInstance();

Now, we will set the hour, minute, second and millisecond to get the closest possible millisecond of the day.

dateNoon.set(Calendar.HOUR_OF_DAY, 12);
dateNoon.set(Calendar.MINUTE, dateNoon.getMinimum(Calendar.MINUTE));
dateNoon.set(Calendar.SECOND, dateNoon.getMinimum(Calendar.SECOND));
// millisecond
dateNoon.set(Calendar.MILLISECOND, dateNoon.getMinimum(Calendar.MILLISECOND));

Example

 Live Demo

import java.util.Calendar;
import java.util.GregorianCalendar;
public class Demo {
   public static void main(String[] argv) throws Exception {
      Calendar dateNoon = Calendar.getInstance();
      // hour, minute and second
      dateNoon.set(Calendar.HOUR_OF_DAY, 12);
      dateNoon.set(Calendar.MINUTE, dateNoon.getMinimum(Calendar.MINUTE));
      dateNoon.set(Calendar.SECOND, dateNoon.getMinimum(Calendar.SECOND));
      // millisecond
      dateNoon.set(Calendar.MILLISECOND, dateNoon.getMinimum(Calendar.MILLISECOND));
      System.out.println(dateNoon.getTime());
   }
}
