Demo Code

import java.text.DateFormatSymbols;
import java.util.Calendar;

public class Main {

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

    // Month is based upon a zero index, January is equal to 0,
    // so we need to add one to the month for it to be in a standard format
    int month = gCal.get(Calendar.MONTH) + 1;
    int day = gCal.get(Calendar.DATE);
    int yr = gCal.get(Calendar.YEAR);

    String dateStr = month + "/" + day + "/" + yr;
    System.out.println(dateStr);//from   w  w  w . j  a va 2s.c o m

    int dayOfWeek = gCal.get(Calendar.DAY_OF_WEEK);

    // Print out the integer value for the day of the week
    System.out.println(dayOfWeek);

    int hour = gCal.get(Calendar.HOUR);
    int min = gCal.get(Calendar.MINUTE);
    int sec = gCal.get(Calendar.SECOND);

    System.out.println(hour + ":" + min + ":" + sec);

    // Create new DateFormatSymbols instance to obtain the String value for dates
    DateFormatSymbols symbols = new DateFormatSymbols();
    String[] days = symbols.getWeekdays();
    System.out.println(days[dayOfWeek]);

    // Get crazy with the date!
    int dayOfYear = gCal.get(Calendar.DAY_OF_YEAR);
    System.out.println(dayOfYear);

    // Print the number of days left in the year
    System.out.println("Days left in " + yr + ": " + (365 - dayOfYear));

    int week = gCal.get(Calendar.WEEK_OF_YEAR);
    // Print the week of the year
    System.out.println(week);

  }
