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
