This questiоn is оn 15 pоints + 5 points for the common rubric described in this exаm’s instructions. Implement the following progrаm in а file named DayOfTheWeek.java that you will upload as response to this question when you are done; Declare three integer variables, all initialized to 0, and respectively named dayOfTheWeek, dayOfTheMonth, and firstDayOfTheMonth. Remember to comment each based on its role (see below for details). 3 points Declare & initialize a Scanner variable named s. 1 point Display the following message on the screen “Please enter an integer representing the date in the current month: ”. 1 point Read an int value from the user and store it in variable dayOfTheMonth. 1 point Decrement dayOfTheMonth by 1 to represent the fact that our formula will assume that we numbers days in a month starting at 0 instead of 1. 1 point Display the following message on the screen “What was the first day of the month? Enter 0 for Monday, 1 for Tuesday…”. 1 point Read an int value from the user and store it in variable firstDayOfTheMonth. 1 point Increment dayOfTheMonth by firstDayOfTheMonth. 1 point Store in the variable dayOfTheWeek the result of computing the modulo of the contents of dayOfTheMonth by 7. 1 point Display the following message on the screen “Today is ”. Make sure that the next information that will be displayed will be on the same line. 1 point Perform the following conditional actions; 3 points Test if dayOfTheWeek is 0, if it is, display “Monday”. Test if dayOfTheWeek is 1, if it is, display “Tuesday”. Test if dayOfTheWeek is 2, if it is, display “Wednesday”. Test if dayOfTheWeek is 3, if it is, display “Thursday”. Test if dayOfTheWeek is 4, if it is, display “Friday”. Test if dayOfTheWeek is 5, if it is, display “Saturday”. Test if dayOfTheWeek is 6, if it is, display “Sunday”. Please note that the above tests may be independent of one another (serial arrangement) or nested. Implement your program using serially arranged conditional statements.
