This article illustrates a Java method for determining the number of days between two dates. Share with you for your reference. The details are as follows:
import java.util.Calendar;
public class DateDifferent{
public static void main(String[] args){
Calendar calendar1 = Calendar.getInstance();
Calendar calendar2 = Calendar.getInstance();
calendar1.set(2007, 01, 10);
calendar2.set(2007, 07, 01);
long milliseconds1 = calendar1.getTimeInMillis();
long milliseconds2 = calendar2.getTimeInMillis();
long diff = milliseconds2 - milliseconds1;
long diffSeconds = diff / 1000;
long diffMinutes = diff / (60 * 1000);
long diffHours = diff / (60 * 60 * 1000);
long diffDays = diff / (24 * 60 * 60 * 1000);
System.out.println("nThe Date Different Example");
System.out.println("Time in milliseconds: " + diff + " milliseconds.");
System.out.println("Time in seconds: " + diffSeconds + " seconds.");
System.out.println("Time in minutes: " + diffMinutes + " minutes.");
System.out.println("Time in hours: " + diffHours + " hours.");
System.out.println("Time in days: " + diffDays + " days.");
}
}
Put the above code in the project to use, [date section] is to complete 24 hours to count as a day, not suitable for the needs of the project, so change this.
public static int getBetweenDay(Date date1, Date date2) {
Calendar d1 = new GregorianCalendar();
d1.setTime(date1);
Calendar d2 = new GregorianCalendar();
d2.setTime(date2);
int days = d2.get(Calendar.DAY_OF_YEAR)- d1.get(Calendar.DAY_OF_YEAR);
System.out.println("days="+days);
int y2 = d2.get(Calendar.YEAR);
if (d1.get(Calendar.YEAR) != y2) {
// d1 = (Calendar) d1.clone();
do {
days += d1.getActualMaximum(Calendar.DAY_OF_YEAR);
d1.add(Calendar.YEAR, 1);
} while (d1.get(Calendar.YEAR) != y2);
}
return days;
}
I hope this article has been helpful to your Java programming.
