Java中ChronoPeriod接口的multipliedBy()方法用於在將給定期間YEAR,MONTH,DAY期間的每個元素乘以“ X”(標量)後,返回ChronoPeriod的新實例。此函數僅在YEAR,MONTHS和DAYS這三個日期都有效。
用法:
public ChronoPeriod multipliedBy(int toMultiply)
參數:此方法接受toMultiply的單個參數,該參數是要乘以周期的標量數。
返回值:在將周期的每個元素與給定的toMultiply輸入相乘之後,此方法返回ChronoPeriod的新實例。
異常:引發ArithmeticException。如果發生數值溢出,則會捕獲此異常。
下麵是上述方法的實現:
程序1:
// Java code to show the function multipliedBy()
// to multiply the given number to given period
import java.time.*;
import java.time.chrono.*;
import java.time.temporal.ChronoUnit;
public class ChronoPeriodClass {
// Function to multiply a constant to given periods
static void multiply(ChronoPeriod p1, int toMultiply)
{
System.out.println(p1.multipliedBy(toMultiply));
}
// 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);
int toMultiply = 2;
multiply(p1, toMultiply);
}
}
輸出:
P8Y22M20D
程序2:
// Java code to show the function multipliedBy()
// to multiply the given number to given period
import java.time.*;
import java.time.chrono.*;
import java.time.temporal.ChronoUnit;
public class ChronoPeriodClass {
// Function to multiply a constant to given periods
static void multiply(ChronoPeriod p1, int toMultiply)
{
System.out.println(p1.multipliedBy(toMultiply));
}
// 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);
int toMultiply = 2;
multiply(p1, toMultiply);
}
}
輸出:
P-8Y-22M-20D
