java.time.chrono.IsoChronology類的getId()方法用於檢索已撤銷getId()方法的特定年代的標識狀態。
用法:
public String getId()
參數:此方法不接受任何參數作為參數。
返回值:此方法返回已撤銷getId()方法的特定年代的標識狀態。
下麵是說明getId()方法的示例:
範例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);
}
}
輸出:
id:ISO
範例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);
}
}
輸出:
id:ISO
