Question

4. (6%) You remembered currentime.java in class that was used to access Calendar.HOUR, Calendar.MINUTE etc. to display time like

The current time is 7:3:11

The current time is 7:3:12

The current time is 7:3:13

Enhance this program to display AM (morning) and PM as well. Run your program once in the morning and once in the afternoon to verify it works.

Can you enhance your program to display the current day and month as well?

Enhance the program to find the duration (say for example, how long it takes to run for loop 1000 times to run animation).

Answer 1

import java.util.Calendar;
public class ShowCurrentTime {

        static final String months[] = { "", "January", "February", "March", "April", "May", "June", "July", "August",
                        "September", "October", "November", "December" };

        public static void main(String[] args) {
                Calendar cal = Calendar.getInstance();

                String time = cal.get(Calendar.DAY_OF_MONTH) 
                                + " " + months[cal.get(Calendar.MONTH)]
                                + " " + cal.get(Calendar.HOUR) 
                                + ":" + cal.get(Calendar.MINUTE) 
                                + ":" + cal.get(Calendar.SECOND)
                                + " " + (cal.get(Calendar.AM_PM) == Calendar.AM ? "AM" : "PM");
                System.out.println(time);
        }

}
