Java优学网Period类详解：轻松计算日期间隔与时间差

LocalDate startDate = LocalDate.of(2020, 3, 15); LocalDate endDate = LocalDate.of(2023, 7, 20);

Period period = Period.between(startDate, endDate);

System.out.println("间隔: " + period.getYears() + "年 " +

               period.getMonths() + "月 " + 
               period.getDays() + "天");

Period twoYearsThreeMonths = Period.of(2, 3, 0); Period fifteenDays = Period.ofDays(15); Period sixMonths = Period.ofMonths(6); Period fiveYears = Period.ofYears(5);

LocalDate projectStart = LocalDate.of(2024, 1, 15); Period developmentPhase = Period.ofMonths(3); LocalDate expectedDelivery = projectStart.plus(developmentPhase);

Period normalized = period.normalized();
