IsoChronology dateNow(ZoneId) method in Java with Example

  • Last Updated : 27 Mar, 2020

The dateNow() method of java.time.chrono.IsoChronology class is used get the current local date according to Iso calendar system from the system clock in the specified time zone.

Syntax:

public LocalDate dateNow(ZoneId zone)

Parameter: This method takes the object of zone id as a parameter.

Return Value: This method returns the local date according to Iso calendar system from the specified clock object.

Below are the examples to illustrate the dateNow() method:



Example 1:




// Java program to demonstrate
// dateNow() method
  
import java.util.*;
import java.io.*;
import java.time.*;
import java.time.chrono.*;
  
public class GFG {
    public static void main(String[] argv)
    {
        try {
            // creating and initializing LocalDate Object
            LocalDate hidate = LocalDate.now();
  
            // getting IsoChronology used in LocalDate
            IsoChronology crono = hidate.getChronology();
  
            // creating and initializing ZoneId object
            ZoneId id = ZoneId.systemDefault();
  
            // getting LocalDate for the
            // given zoneid object
            // by using dateNow() method
            LocalDate date = crono.dateNow(id);
  
            // display the result
            System.out.println("LocalDate is: "
                               + date);
        }
        catch (DateTimeException e) {
            System.out.println("passed parameter can"
                               + " not form a date");
            System.out.println("Exception thrown: " + e);
        }
    }
}
Output:
LocalDate is: 2020-03-08

Example 2:




// Java program to demonstrate
// dateNow() method
  
import java.util.*;
import java.io.*;
import java.time.*;
import java.time.chrono.*;
  
public class GFG {
    public static void main(String[] argv)
    {
        try {
            // creating and initializing LocalDate Object
            LocalDate hidate = LocalDate.now();
  
            // getting IsoChronology used in LocalDate
            IsoChronology crono = hidate.getChronology();
  
            // creating and initializing ZoneId object
            ZoneId id = ZoneId.of("Europe/Paris");
  
            // getting LocalDate for the
            // given zoneid object
            // by using dateNow() method
            LocalDate date = crono.dateNow(id);
  
            // display the result
            System.out.println("LocalDate is: "
                               + date);
        }
        catch (DateTimeException e) {
            System.out.println("passed parameter can"
                               + " not form a date");
            System.out.println("Exception thrown: " + e);
        }
    }
}
Output:
LocalDate is: 2020-03-08
