這篇文章主要介紹了如何在Java中獲取當(dāng)天零點(diǎn)和明天零點(diǎn)的時(shí)間和時(shí)間戳,并提供了示例代碼,新手小白完全可以通過(guò)文中介紹的代碼實(shí)現(xiàn),需要的朋友可以參考下

Java獲取當(dāng)天零點(diǎn)和明天零點(diǎn)的時(shí)間和時(shí)間戳

//1.獲取當(dāng)前時(shí)間
LocalDate today = LocalDate.now();
//2.轉(zhuǎn)換成LocalDateTime對(duì)象
LocalDateTime todayMidnight = LocalDateTime.of(today, LocalTime.MIN);
System.out.println("當(dāng)天0點(diǎn)0分0秒的時(shí)間:"+todayMidnight);
//3.將LocalDateTime對(duì)象轉(zhuǎn)換成時(shí)間戳
long startTime = todayMidnight.atZone(ZoneId.systemDefault()).toInstant().toEpochMilli();
System.out.println("當(dāng)天0點(diǎn)0分0秒的時(shí)間戳:"+startTime);

//1.獲取當(dāng)前日期+1天
LocalDate tomorrow = today.plusDays(1);
//2.獲取明天的時(shí)間
LocalDateTime tomorrowMidnight=tomorrow.atStartOfDay();
System.out.println("第二天0點(diǎn)0分0秒時(shí)間:"+tomorrowMidnight);
//3.將LocalDateTime對(duì)象轉(zhuǎn)換成時(shí)間戳
long endTime = tomorrowMidnight.atZone(ZoneId.systemDefault()).toInstant().toEpochMilli();
System.out.println("第二天0點(diǎn)0分0秒的時(shí)間戳:"+endTime);

        System.out.println("第二天0點(diǎn)0分0秒的時(shí)間戳:"+endTime);
    }
