Java中的LocalDate直到()方法
可以使用until()
Java中LocalDate类中的方法获得两个LocalDate对象之间的差异。此方法需要一个参数,即LocalDate对象的结束日期,并且使用Period对象返回两个LocalDate对象之间的差额。
演示此过程的程序如下:
示例
import java.time.*; public class Demo { public static void main(String[] args) { LocalDate ld1 = LocalDate.parse("2019-01-10"); LocalDate ld2 = LocalDate.parse("2019-02-14"); System.out.println("The first LocalDate is: " + ld1); System.out.println("The second LocalDate is: " + ld2); System.out.println("The difference between two LocalDates is: " + ld1.until(ld2)); } }
输出结果
The first LocalDate is: 2019-01-10 The second LocalDate is: 2019-02-14 The difference between two LocalDates is: P1M4D
现在让我们了解上面的程序。
首先,显示两个LocalDate对象。然后使用until()
方法获得它们之间的差异并显示出来。演示此代码段如下所示:
LocalDate ld1 = LocalDate.parse("2019-01-10"); LocalDate ld2 = LocalDate.parse("2019-02-14"); System.out.println("The first LocalDate is: " + ld1); System.out.println("The second LocalDate is: " + ld2); System.out.println("The difference between two LocalDates is: " + ld1.until(ld2));
