Java中的 ChronoPeriod getChronology() 方法及示例
Java中ChronoPeriod接口的getChronology()方法用来获取这个Period的年表,也就是ISO日历系统。
句法:
ChronoPeriod getChronology()
参数:此方法不接受任何参数。
返回值:此方法返回此的字符串表示
下面的程序说明了上述方法:
程序 1 :
// Java code to show the getChronology() function
import java.time.*;
import java.time.chrono.*;
import java.time.temporal.ChronoUnit;
public class ChronoPeriodClass {
// Function to negate given periods
static void printChronology(ChronoPeriod p1)
{
System.out.println(p1.getChronology());
}
// Driver Code
public static void main(String[] args)
{
// Defining period
int year = 4;
int months = 11;
int days = 10;
ChronoPeriod p1 = Period.of(year, months, days);
printChronology(p1);
}
}
输出:
ISO
方案二:
// Java code to show the getChronology() function
import java.time.*;
import java.time.chrono.*;
import java.time.temporal.ChronoUnit;
public class ChronoPeriodClass {
// Function to negate given periods
static void printChronology(ChronoPeriod p1)
{
System.out.println(p1.getChronology());
}
// Driver Code
public static void main(String[] args)
{
// Defining period
int year = -4;
int months = -11;
int days = -10;
ChronoPeriod p1 = Period.of(year, months, days);
printChronology(p1);
}
}
输出:
ISO
