TimeZone useDaylightTime() method in Java with Examples

The useDaylightTime() method of TimeZone class is used perform a query on this time zone to know whether it uses the daylight saving time. Syntax:

public abstract boolean useDaylightTime()

Parameters: The method does not accept any parameters. Return Value: The method returns either of the two boolean values:

‘true’ if this time zone uses daylight saving time
‘false’ if this time zone does not use daylight saving time

Below program demonstrates the above-mentioned function: Example 1:

Java

// Program to demonstrate the
// useDaylightTime()

import java.util.*;

public class GFG {

    public static void main(String[] args)
    {

        // Create TimeZone object
        TimeZone obj
            = TimeZone.getTimeZone("Europe/Rome");

        // Checking day light time
        // and displaying the result
        System.out.println("Day light time is = "
                           + obj.useDaylightTime());
    }
}

Output:

Day light time is = true

Example 2:

Java

// Program to demonstrate the
// useDaylightTime()

import java.util.*;

public class GFG {

    public static void main(String[] args)
    {

        // Create TimeZone object
        TimeZone obj
            = TimeZone.getTimeZone("Pacific/Pago_Pago");

        // checking day light time
        // and printing the result
        System.out.println("Day light time is = "
                           + obj.useDaylightTime());
    }
}

Output:

Day light time is = false
