Calculating days between two dates with Java

Question

I want a Java program that calculates days between two dates.

1. Type the first date (German notation; with whitespaces: \"dd mm yyyy\")
2. Type the second

Answer 1

Use:

public int getDifferenceDays(Date d1, Date d2) {
    int daysdiff = 0;
    long diff = d2.getTime() - d1.getTime();
    long diffDays = diff / (24 * 60 * 60 * 1000) + 1;
    daysdiff = (int) diffDays;
    return daysdiff;
}
