首先,让我们迅速回顾一下 Thread.sleep() 的基本用法及其潜在问题。在一些简单的定时任务场景中,开发者可能使用 Thread.sleep(milliseconds) 方法,以每隔一定时间检查状态,如下示例所示: public static boolean FLAG = false; public static void main(String[] args) throws InterruptedException { while (true) { Th...
首先,将毫秒数除以1000以获得秒数。 然后,将秒数除以60以获得分钟数。 最后,将分钟数和秒数取余数以获得秒数。 以下是一个Java代码示例: 代码语言:java 复制 publicclassMillisecondsToMinutesAndSeconds{publicstaticvoidmain(String[]args){longmilliseconds=123456;StringformattedTime=convertMillisecondsToMinutesA...

long differenceInDays = TimeUnit.MILLISECONDS.toDays(differenceInMilliseconds); System.out.println("天数差值:" + differenceInDays + "天"); 二,Calendar类型 1,获取当前日期及和Date类型转化 Calendar类,专门用于转换特定时刻和日历字段之间的日期和时间。
