原文:https://www . geesforgeks . org/period-get units-method-in-Java-with-examples/
Java 中 Period 类的 getUnits()方法用来获取这个 Period 支持的单位集。支持的单位是列表中的年、月、日(仅按此顺序)。
语法:
public List getUnits()
参数:该方法不接受任何参数。
返回值该方法返回包含年、月、日的列表。
下面的程序说明了上述方法:
程序 1 :
// Java code to show the function getUnits()
// to get the set of units supported by period
import java.time.Period;
import java.time.temporal.ChronoUnit;
public class PeriodDemo {
// Function to get the set of units supported by period
static void getNumberOfDays(int year, int months, int days)
{
Period period = Period.of(year, months, days);
System.out.println(period.getUnits());
}
// Driver Code
public static void main(String[] args)
{
int year = 1;
int months = 13;
int days = 36;
getNumberOfDays(year, months, days);
}
}
输出:
[Years, Months, Days]
程序二 :
// Java code to show the function getUnits()
// to get the set of units supported by period
import java.time.Period;
import java.time.temporal.ChronoUnit;
public class PeriodDemo {
// Function to get the set of units supported by period
static void getNumberOfDays(int year, int months, int days)
{
Period period = Period.ofDays(days);
System.out.println(period.getUnits());
}
// Driver Code
public static void main(String[] args)
{
int year = 0;
int months = 0;
int days = 0;
getNumberOfDays(year, months, days);
}
}
输出:
[Years, Months, Days]
