of week in Java. As we know that GregorianCalendar provides the
current date, month and year in a yearly calendar. Use the Calendar

Description of program:
The following program helps us in getting the first day
of the week. For getting first day we need an object of GragorianCalendar.
With the help of this we calculate the first day of week using
the getFirstDayOf Week() and getActualMaximum(Calendar.DAY_OF_WEEK)
methods that matches the case. If any of these will match, it will display the
actual day that displays like the following output.
Description of code:
getActualMaximum(int field):
This method return the maximum value according to its field. It takes one
field like: DAY_OF_WEEK, DAY_OF_MONTH etc.
getFirstDayOfWeek():
This is the method that is used to get the first day of the week.

public static void main(String[] args) {
GregorianCalendar gcal = new GregorianCalendar();
int week = gcal.getActualMaximum(Calendar.DAY_OF_WEEK);
System.out.println("Day of week: " + week);
int first = gcal.getFirstDayOfWeek() ;
switch(first){
case 1:
System.out.println("Sunday");
break;
case 2:
System.out.println("Monday");
