IsoChronology dateNow(Clock) method in Java with Example

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

Syntax:

public LocalDate dateNow(Clock clock)

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

Return Value: This method returns the LocalDate according to Hijrah 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 clock object
            Clock clock = Clock.systemUTC();

            // getting LocalDate for the
            // given clock object
            // by using dateNow() method
            LocalDate date = crono.dateNow(clock);

            // 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 clock object
            Clock clock = Clock.systemUTC();

            // setting clock
            clock = Clock.tick(clock,
                               Duration.ofDays(100));

            // getting LocalDate for the
            // given clock object
            // by using dateNow() method
            LocalDate date = crono.dateNow(clock);

            // 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: 2020-02-08
