The getId() method of java.time.chrono.IsoChronology class is used to retrieve the identification status for the particular chronology for which getId() method is revoked.
Syntax:
public String getId()
Parameter: This method does not accept any argument as a parameter.
Return Value: This method returns the identification status for the particular chronology for which getId() method is revoked.
Below are the examples to illustrate the getId() method:
Example 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);
}
} |
Output:
id : ISO
Example 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);
}
} |
Output:
id : ISO
