Java如何获取当天零点和明天零点的时间和时间戳

//1.获取当前时间
LocalDate today = LocalDate.now();
//2.转换成LocalDateTime对象
LocalDateTime todayMidnight = LocalDateTime.of(today, LocalTime.MIN);
System.out.println("当天0点0分0秒的时间:"+todayMidnight);
//3.将LocalDateTime对象转换成时间戳
long startTime = todayMidnight.atZone(ZoneId.systemDefault()).toInstant().toEpochMilli();
System.out.println("当天0点0分0秒的时间戳:"+startTime);

//1.获取当前日期+1天
LocalDate tomorrow = today.plusDays(1);
//2.获取明天的时间
LocalDateTime tomorrowMidnight=tomorrow.atStartOfDay();
System.out.println("第二天0点0分0秒时间:"+tomorrowMidnight);
//3.将LocalDateTime对象转换成时间戳
long endTime = tomorrowMidnight.atZone(ZoneId.systemDefault()).toInstant().toEpochMilli();
System.out.println("第二天0点0分0秒的时间戳:"+endTime);
