Java code to greet the user based on the current time.

Here I am going to explain, how to get the current date and time using java code. Also, based on the current time how to greet the user good morning, good evening etc.

import java.util.Calendar;
import java.util.GregorianCalendar;

public class DisplayDateTime {
 public static void main(String[] args) {
  GregorianCalendar time = new GregorianCalendar();
  int hour = time.get(Calendar.HOUR_OF_DAY);
  int min = time.get(Calendar.MINUTE);
  int day = time.get(Calendar.DAY_OF_MONTH);
  int month = time.get(Calendar.MONTH) + 1;
  int year = time.get(Calendar.YEAR);

  System.out.println("The current time is \t" + hour + ":" + min);
  System.out.println("Today's date is \t" + month + "/" + day + "/"
    + year);

  if (hour < 12)
   System.out.println("Good Morning!");
  else if (hour < 17 && !(hour == 12))
   System.out.println("Good Afternoon");
  else if (hour == 12)
   System.out.println("Good Noon");
  else
   System.out.println("Good Evening");
 }
}

Output:

The current time is  12:2
Today's date is  8/20/2013
Good Noon
