Java计算两个日期时间之间的天数最简方法

  /**
   * 计算两个时间点之间的天数
   */
  private static void getBetweenDay() {
    LocalDate start = LocalDate.of(2018, 2, 12);
    LocalDate now = LocalDate.now();
    System.out.println("两个时间之间的天数是：" + TimesUtils.getBetweenDay(start, now) + " 天。");
  }
  
  /**
   * 计算两个时间点之间的天数
   */
  public static long getBetweenDay(LocalDate start, LocalDate end) {
    return end.toEpochDay() - start.toEpochDay();
  }
