计算LocalDateTime相差的天数，24小时为单位，取模计算
代码语言：javascript复制package com.example.core.mydemo.java2;
import java.time.LocalDateTime;
import java.time.temporal.ChronoUnit;
public class LocalDateTimeTest {
public static void main(String[] args) {
LocalDateTime dateTime1 = LocalDateTime.of(2024, 7, 1, 12, 0);
LocalDateTime dateTime2 = LocalDateTime.of(2024, 7, 3, 11, 0);
// long daysBetween = ChronoUnit.DAYS.between(dateTime1, dateTime2);
long daysBetween = 1; //默认
long hoursBetween = ChronoUnit.HOURS.between(dateTime1, dateTime2);
System.out.println("相差小时数: " hoursBetween);
System.out.println("11=" (hoursBetween / 24));
System.out.println("11=" (hoursBetween % 24));
if(hoursBetween <= 24){
