Example:

// Java program to demonstrate the example 
// of boolean useDaylightTime() method 
// of TimeZone 

import java.util.*;

public class UseDaylightTimeOfTimeZone {
    public static void main(String args[]) {
        // Instantiates two TimeZone object
        TimeZone tz = TimeZone.getTimeZone("Africa/Asmera");

        // Display tz
        System.out.println("tz: " + tz);


        // By using useDaylightTime() method is to
        // check whether time zone tz use daylight time or
        // not
        boolean status = tz.useDaylightTime();

        System.out.print("tz.useDaylightTime(): ");
        System.out.println(status);
    }
}

Output

tz: sun.util.calendar.ZoneInfo[id="Africa/Asmera",offset=10800000,dstSavings=0,useDaylight=false,transitions=6,lastRule=null]
tz.useDaylightTime(): false
