兩個 LocalTime 之間的時間量
計算兩個 LocalTime
:(1)到 until(Temporal, TemporalUnit)
方法和(2)TemporalUnit.between(Temporal, Temporal)
之間的時間單位有兩種等效方法。
import java.time.LocalTime;
import java.time.temporal.ChronoUnit;
public class AmountOfTime {
public static void main(String[] args) {
LocalTime start = LocalTime.of(1, 0, 0); // hour, minute, second
LocalTime end = LocalTime.of(2, 10, 20); // hour, minute, second
long halfDays1 = start.until(end, ChronoUnit.HALF_DAYS); // 0
long halfDays2 = ChronoUnit.HALF_DAYS.between(start, end); // 0
long hours1 = start.until(end, ChronoUnit.HOURS); // 1
long hours2 = ChronoUnit.HOURS.between(start, end); // 1
long minutes1 = start.until(end, ChronoUnit.MINUTES); // 70
long minutes2 = ChronoUnit.MINUTES.between(start, end); // 70
long seconds1 = start.until(end, ChronoUnit.SECONDS); // 4220
long seconds2 = ChronoUnit.SECONDS.between(start, end); // 4220
long millisecs1 = start.until(end, ChronoUnit.MILLIS); // 4220000
long millisecs2 = ChronoUnit.MILLIS.between(start, end); // 4220000
long microsecs1 = start.until(end, ChronoUnit.MICROS); // 4220000000
long microsecs2 = ChronoUnit.MICROS.between(start, end); // 4220000000
long nanosecs1 = start.until(end, ChronoUnit.NANOS); // 4220000000000
long nanosecs2 = ChronoUnit.NANOS.between(start, end); // 4220000000000
// Using others ChronoUnit will be thrown UnsupportedTemporalTypeException.
// The following methods are examples thereof.
long days1 = start.until(end, ChronoUnit.DAYS);
long days2 = ChronoUnit.DAYS.between(start, end);
