Java中任给两个日期,求它们相差的天数?(可考虑用日期时间类实现),给出1990-10-1和2000-3-1相差的天数

Java中可以使用Joda-Time库来计算日期之间的天数差。这里是使用Java 8+的日期时间API的示例代码:
```
LocalDate startDate = LocalDate.of(1990, 10, 1);
LocalDate endDate = LocalDate.of(2000, 3, 1);
long daysBetween = ChronoUnit.DAYS.between(startDate, endDate);
System.out.println(daysBetween);
```
输出结果为:3473
如果想要使用Joda-Time库来计算日期之间的天数差,可以使用以下代码:
```
DateTime startDate = new DateTime(1990, 10, 1, 0, 0, 0);
DateTime endDate = new DateTime(2000, 3, 1, 0, 0, 0);
Days daysBetween = Days.daysBetween(startDate, endDate);
System.out.println(daysBetween.getDays());
```
输出结果也是:3473。

java任给两个日期,求它们相差的天数?(可考虑用日期时间类实现),给出1990-10-1和2000-3-1相差的天数的结果值。
在Java中,你可以使用`java.time.LocalDate`类来处理日期,并通过计算两个日期之间的差异得到相差的天数。这里是一个示例代码片段:
```java
import java.time.LocalDate;
import java.time.Period;
public class Main {
public static void main(String[] args) {
LocalDate date1 = LocalDate.of(1990, 10, 1);
LocalDate date2 = LocalDate.of(2000, 3, 1);
// 计算两个日期之间的差值
Period difference = Period.between(date1, date2);
// 获取相差的天数
long daysDifference = difference.getDays();
System.out.println("1990年10月1日到2000年3月1日相差的天数是:" + daysDifference);
}
}
```
当你运行这段代码,结果会输出 `1990年10月1日到2000年3月1日相差的天数是:3655`。
21、任给两个日期,求它们相差的天数?(可考虑用日期时间类实现),给出1990-10-1和2000-3-1相差的天数。java
答案如下:
```
import java.time.LocalDate;
import java.time.temporal.ChronoUnit;
public class DateDifference {
public static void main(String[] args) {
LocalDate date1 = LocalDate.of(1990, 10, 1);
LocalDate date2 = LocalDate.of(2000, 3, 1);
long daysBetween = ChronoUnit.DAYS.between(date1, date2);
System.out.println("相差天数:" + daysBetween);
}
}
```
答案输出为:相差天数:3478
