Java获取当日的起始时间和结束时间

//获取0点

public static Date getStartTime() {Calendar todayStart = Calendar.getInstance();todayStart.set(Calendar.HOUR_OF_DAY, 0);todayStart.set(Calendar.MINUTE, 0);todayStart.set(Calendar.SECOND, 0);todayStart.set(Calendar.MILLISECOND, 0);return todayStart.getTime();}

//获取23点

public static Date getnowEndTime() {Calendar todayEnd = Calendar.getInstance();todayEnd.set(Calendar.HOUR_OF_DAY, 23);todayEnd.set(Calendar.MINUTE, 59);todayEnd.set(Calendar.SECOND, 59);todayEnd.set(Calendar.MILLISECOND, 999);return todayEnd.getTime();}

博客中有一篇帖子也是获取当日的起始时间和结束时间的，但是写法错误，特发布正确的写法
