Java 8: Difference between two LocalDateTime in multiple units

To find the difference between two LocalDateTime objects in multiple units, you can use the Duration class. Here's an example of how you can use Duration to find the difference between two LocalDateTime objects in days, hours, and minutes:

LocalDateTime start = LocalDateTime.of(2020, Month.JANUARY, 1, 0, 0);
LocalDateTime end = LocalDateTime.of(2020, Month.JANUARY, 3, 12, 30);

Duration duration = Duration.between(start, end);

long days = duration.toDays();
long hours = duration.toHours();
long minutes = duration.toMinutes();

System.out.println("Days: " + days);
System.out.println("Hours: " + hours);
System.out.println("Minutes: " + minutes);

This will print the following output:

Days: 2
Hours: 36
Minutes: 2190

You can also use the Period class to find the difference between two LocalDateTime objects in years, months, and days. Here's an example of how you can use Period:

LocalDateTime start = LocalDateTime.of(2020, Month.JANUARY, 1, 0, 0);
LocalDateTime end = LocalDateTime.of(2022, Month.JANUARY, 3, 12, 30);

Period period = Period.between(start.toLocalDate(), end.toLocalDate());

int years = period.getYears();
int months = period.getMonths();
int days = period.getDays();

System.out.println("Years: " + years);
System.out.println("Months: " + months);
System.out.println("Days: " + days);

This will print the following output:

Years: 2
Months: 0
Days: 2
