Java中的句点 getYears() 方法和示例
Java中 Period 的 getYears() 方法用于获取此期间所使用的年数。
注意: 15 个月不等于 1 年零 3 个月。
句法:
public List getYears()
参数:此方法不接受任何参数。
返回:此方法返回当前期间的年数。
下面的程序说明了上述方法:
程序 1 :
// Java code to show the function getYears()
// to get the number of years in the period
import java.time.Period;
import java.time.temporal.ChronoUnit;
public class PeriodDemo {
// Function to get the number of years
static void getNumberOfDays(int year, int months, int days)
{
Period period = Period.of(year, months, days);
System.out.println(period.getYears());
}
// Driver Code
public static void main(String[] args)
{
int year = 12;
int months = 3;
int days = 31;
getNumberOfDays(year, months, days);
}
}
输出:
12
方案二:
// Java code to show the function getYears()
// to get the number of years in the period
import java.time.Period;
import java.time.temporal.ChronoUnit;
public class PeriodDemo {
// Function to get the number of years
static void getNumberOfDays(int year, int months, int days)
{
Period period = Period.of(year, months, days);
System.out.println(period.getYears());
}
// Driver Code
public static void main(String[] args)
{
int year = -12;
int months = 3;
int days = 31;
getNumberOfDays(year, months, days);
}
}
输出:
-12
