`LocalDateTimeUtil.between` 是一个自定义的工具类或方法,用于计算两个 `LocalDateTime` 对象之间的时间间隔。这个方法可能会计算两个 `LocalDateTime` 之间的天数、小时数、分钟数等等。
一般来说,这个方法的实现会使用 `Duration` 或者 `Period` 类来计算时间间隔。`Duration` 用于计算时长,例如小时、分钟和秒,而 `Period` 用于计算日期之间的天数差。
请注意,`LocalDateTimeUtil.between` 是一个自定义的方法,可能在不同的项目中具有不同的实现。如果你想使用这个方法,你可能需要查看你所使用的项目的相关文档,或者自己实现一个类似的方法。

LocalDateTimeUtil.between获取间隔后,转化为时分格式的字符串
您好!没问题,我明白您的问题,可以为您解答。
您可以先使用 LocalDateTimeUtil.between 方法获取两个日期时间之间的 Duration 对象,然后使用 Duration 对象的 toHours() 和 toMinutes() 方法分别获取小时数和分钟数。最后,将这些数值结合起来,用 String.format 方法转化为想要的时分格式的字符串即可。
示例代码:
``` java
LocalDateTime start = LocalDateTime.of(2021, 8, 1, 10, 0);
LocalDateTime end = LocalDateTime.of(2021, 8, 1, 13, 30);
Duration duration = LocalDateTimeUtil.between(start, end);
long hours = duration.toHours();
long minutes = duration.toMinutes() % 60;
String formatted = String.format("%d小时%d分钟", hours, minutes);
System.out.println(formatted); // 输出:3小时30分钟
```

LocalDateTimeUtil.of(date).withDayOfMonth(i)
根据提供的引用内容,我们可以看出`LocalDateTimeUtil.of(date).withDayOfMonth(i)`是一个自定义的方法,它的作用是将传入的`date`转换为`LocalDateTime`对象,并将其日期修改为`i`号。具体实现代码如下:
```java
public static LocalDateTime of(Date date) {
return LocalDateTime.ofInstant(date.toInstant(), ZoneId.systemDefault());
}
public static LocalDateTime of(Date date, ZoneId zone) {
return LocalDateTime.ofInstant(date.toInstant(), zone);
