Java 中从()方法开始的时间段，示例
原文:https://www . geesforgeks . org/period-from-in-method-in-Java-with-examples/
Java 中 Period 类的 from()方法用于从给定的时间量中获取 Period 的实例。
此函数根据参数中给出的数量获得一个周期。时间计数表示时间量，可以是基于日期的，也可以是基于时间的。
语法:
public static Period from(TemporalAmount amount)
参数:此方法接受单个参数量。这个金额是我们需要转换成期间的金额。
返回值:该函数返回与给定金额相等的期间。
异常:
- Date-time exception –If it cannot be converted into a period, a date-time exception will be thrown.
- Arithmetic exception –If the number of years, months or days exceeds an integer, it will throw an arithmetic exception.
下面程序举例说明上面的方法:
// Java code to show the function from()
// which represents the period of given amount
import java.time.Period;
public class PeriodClassGfG {
// Function to convert given amount to period
static void convertToPeriod(int year, int months, int days)
{
Period period = Period.from(Period.of(year, months, days));
System.out.println(period);
}
// Driver code
public static void main(String[] args)
{
int year = 20, months = 13, days = 17;
Period period = Period.from(Period.of(year, months, days));
convertToPeriod(year, months, days);
}
}
输出:
P20Y13M17D
