Java中Period类的minusDays()方法用于从该Period中减去天数。此功能仅在DAYS运行,不影响YEAR和MONTH。

用法:

public Period minusDays(long daysToSubtract)

参数:此方法接受单个参数daysToSubtract,这是要从该期间中减去的天数。

返回值:此方法根据输入中提供的时间段返回一个时间段

减去指定的天数。不能为空。

异常:它引发ArithmeticException。如果发生数字溢出,则会捕获此异常。

以下示例程序旨在说明上述方法:

程序1:

// Java code to show the function minusDays()

// to subtract the number of days from given periods

import java.time.Period;

import java.time.temporal.ChronoUnit;

public class PeriodClass {

// Function to subtract two given periods

static void subtractDays(Period p1, int daystoSubtract)

{

System.out.println(p1.minusDays(daystoSubtract));

}

// Driver Code

public static void main(String[] args)

{

// Defining first period

int year = 4;

int months = 11;

int days = 10;

Period p1 = Period.of(year, months, days);

int daystoSubtract = 8;

subtractDays(p1, daystoSubtract);

}

}

输出:

P4Y11M2D

程序2:

// Java code to show the function minusDays()

// to subtract the number of days from given periods

import java.time.Period;

import java.time.temporal.ChronoUnit;

public class PeriodClass {

// Function to subtract two given periods

static void subtractDays(Period p1, int daystoSubtract)

{

System.out.println(p1.minusDays(daystoSubtract));

}

// Driver Code

public static void main(String[] args)

{

// Defining first period

int year = -4;

int months = -11;

int days = 0;

Period p1 = Period.of(year, months, days);

int daystoSubtract = 8;

subtractDays(p1, daystoSubtract);

}

}

输出:

P-4Y-11M-8D
