Java中的 IsoChronology getId() 方法与示例
Java.time.chrono.IsoChronology 类的getId()方法用于检索撤销 getId() 方法的特定年表的标识状态。
句法:
public String getId()
参数:此方法不接受任何参数作为参数。
返回值:此方法返回 getId() 方法被撤销的特定年表的标识状态。
以下是说明getId()方法的示例:
示例 1:
// Java program to demonstrate
// getId() method
import java.util.*;
import java.io.*;
import java.time.*;
import java.time.chrono.*;
public class GFG {
public static void main(String[] argv)
{
// creating and initializing
// LocalDate Object
LocalDate hidate = LocalDate.now();
// getting IsoChronology
// used in LocalDate
IsoChronology crono
= hidate.getChronology();
// getting id of this Chronology
// by using getId() method
String id = crono.getId();
// display the result
System.out.println("id : " + id);
}
}
输出:
id : ISO
示例 2:
// Java program to demonstrate
// getId() method
import java.util.*;
import java.io.*;
import java.time.*;
import java.time.chrono.*;
public class GFG {
public static void main(String[] argv)
{
// creating and initializing
// LocalDate Object
LocalDate hidate = LocalDate.now(Clock.systemDefaultZone());
// getting IsoChronology
// used in LocalDate
IsoChronology crono
= hidate.getChronology();
// getting id of this Chronology
// by using getId() method
String id = crono.getId();
// display the result
System.out.println("id : " + id);
}
}
输出:
id : ISO
