CMIS 141 Write a program to display a calendar for any month of any year of the twentieth century and on. User enters the month number (must be between 1 and 12) and the year (must be 1900 or later). Example, say month 2 and year 2002 are input, then this is displayed in a JTextArea in a JOptionPane: February 2002 Su Mo Tu We Th Fr Sa 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 -------------------------------------------------------- To determine the day of the week on which the month starts: know that January 1, 1900 was a Monday, and then find the number of days difference between that day and the first day of the month for which you are making the calendar. This difference plus one mod 7 (i.e. (totaldays+1) % 7) tells you the day of the week (0 meaning Sunday, 1 meaning Monday etc.). Finding the number of days from 1/1/1900 to the first day of any other month can be further broken down into the following subproblems: 1. Number of days in whole years (i.e., (Year - 1900) * 365); 2. One day for each year in the above range which is a leap year; 3. The number of days in each month from January thru the previous month of the year you're making a month calendar for. Your program must use this technique to determine the start day of the month. Remember the rule for leap years: A year is a leap year if it is divisible by 4, unless it is divisible by 100 (in which case it's not a leap year) UNLESS it's also divisible by 400 (in which case it's a leap year). year%4==0 && year%100!=0 || year%400==0 (1900 was not a leap year, but 2000 is, 2100 will not be). The program's overall structure will be something like: input a valid month number, input a valid year number, calculate the total number of days since 1900-1-1, append the month days to a JTextArea, Displaying the dates hint: have a loop that displays the blank days of the first week, then have a loop that loops over the days 1 to 30 (or 31, 28, or 29) The end of the week is when the date plus the number of blank days is a multiple of 7.
