java查两个日期之间的天数

要在Java中计算两个日期之间的天数，可以使用java.time包中的LocalDate类和ChronoUnit枚举。具体做法如下所示：

1. 导入所需的类和枚举：

   import java.time.LocalDate;
   import java.time.temporal.ChronoUnit;

2. 定义两个日期对象：

   LocalDate date1 = LocalDate.of(2023, 4, 18);
   LocalDate date2 = LocalDate.of(2023, 5, 10);

3. 使用ChronoUnit.DAYS.between()方法计算两个日期之间的天数：

   long daysBetween = ChronoUnit.DAYS.between(date1, date2);

4. 打印结果：

   System.out.println("相差天数: " + daysBetween);

完整的代码示例如下所示：

import java.time.LocalDate;
import java.time.temporal.ChronoUnit;

public class DateDifference {
    public static void main(String[] args) {
        LocalDate date1 = LocalDate.of(2023, 4, 18);
        LocalDate date2 = LocalDate.of(2023, 5, 10);
        
        long daysBetween = ChronoUnit.DAYS.between(date1, date2);
        System.out.println("相差天数: " + daysBetween);
    }
}

你可以将你要比较的两个日期替换成具体的日期，运行代码后就可以得到它们之间的天数差。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
