Java 中的计时减()方法,示例
原文:https://www . geeksforgeeks . org/chronoperiod-减去方法-in-java-with-examples/
Java 中计时周期类的减()方法用于从指定的周期中减去给定的周期量。该功能在年、月和日分别运行。
注意:不进行归一化。12 个月和 1 年是不同的。
语法:
ChronoPeriod minus(TemporalAmount amountToSubtract)
参数:该方法接受单个参数 amountToSubtract ,即从该周期减去的量。它不能为空。
返回值:该方法根据给定的周期,减去请求的周期,返回一个计时周期,并且不能为空。
例外:
- Date and time exception : If the specified amount has a non-ISO chronology or contains invalid units, this exception will be returned.
- Arithmetic exception : If there is a numerical overflow, catch the exception.
下面的程序说明了上述方法:
程序 1 :
// Java code to show the function minus()
// to subtract the two given periods
import java.time.*;
import java.time.chrono.*;
import java.time.temporal.ChronoUnit;
public class ChronoPeriodDemo {
// Function to subtract two given periods
static void subtractChronoPeriod(ChronoPeriod p1, ChronoPeriod p2)
{
System.out.println(p1.minus(p2));
}
// Driver Code
public static void main(String[] args)
{
// Defining first period
int year = 4;
int months = 11;
int days = 10;
ChronoPeriod p1 = Period.of(year, months, days);
// Defining second period
int year1 = 2;
int months1 = 7;
int days1 = 8;
ChronoPeriod p2 = Period.of(year1, months1, days1);
subtractChronoPeriod(p1, p2);
}
}
输出:
P2Y4M2D
程序二 :
// Java code to show the function minus()
// to subtract the two given periods
import java.time.*;
import java.time.chrono.*;
import java.time.temporal.ChronoUnit;
public class ChronoPeriodDemo {
// Function to subtract two given periods
static void subtractChronoPeriod(ChronoPeriod p1, ChronoPeriod p2)
{
System.out.println(p1.minus(p2));
}
// Driver Code
public static void main(String[] args)
{
// Defining second period
int year1 = 2;
int months1 = 7;
int days1 = 8;
ChronoPeriod p1 = Period.of(year1, months1, days1);
// Defining first period
int year = 4;
int months = 11;
int days = 10;
ChronoPeriod p2 = Period.of(year, months, days);
subtractChronoPeriod(p1, p2);
}
}
输出:
P-2Y-4M-2D
