Solution
Here is a simple Java program that prints the current time in GMT:
import java.util.Calendar;
import java.util.TimeZone;
public class Main {
public static void main(String[] args) {
// Create a Calendar object
Calendar calendar = Calendar.getInstance();
// Set the time zone to GMT
TimeZone timeZone = TimeZone.getTimeZone("GMT");
calendar.setTimeZone(timeZone);
// Get the current time in GMT
int hour = calendar.get(Calendar.HOUR_OF_DAY);
int minute = calendar.get(Calendar.MINUTE);
int second = calendar.get(Calendar.SECOND);
// Print the current time in GMT
System.out.println("Current time in GMT is " + hour + ":" + minute + ":" + second);
}
}
This program first creates a Calendar object, which provides methods for getting and setting date and time fields such as YEAR, MONTH, HOUR, etc. Then it sets the time zone of the Calendar object to GMT using the setTimeZone method. After that, it gets the current hour, minute, and second in GMT using the get method of the Calendar object. Finally, it prints the current time in GMT.
