Problem: Write a program that prints the calendar for a given year. The user will be promoted to choose the calendar for the month or the year. If the year is selected, then the calendar for the given year will be displayed. If the month is selected then the user will be prompted to enter the month, then the calendar for the given month will be displayed. Top down design: Break down the problem into sub problems and state what you will achieve for each of the sub problems First we need to break down into two sub problems. 1. Get the users input a. Read the input(year) 2. Print the calendar Print the calendar for the year a. Print the calendar for each month of the year i. Print the title for each month in the year. 1. Print the month and the year 2. Print Sunday Monday Tuesday Wednesday Thursday Friday Saturday. ii. Print the body for the month 1. Get the number of the days for each month of the year 2. Need to know if the year is a leap year or not. A year is a leap year if it is divisible by 400 or if the year is divisible by 4 but not divisible by 100 3. Get the number for the first day in the month. For example, November 1st was on a Saturday which is the 6th day of the week assuming that Sunday is the zero day of the week. To figure out which day is the first day of the month you need to do the following: a. Calculate the total number of days since 1800 up to the month of the year that you are trying to print the calendar i. Calculate the total number of days since 1800 up to one year prior to the given year. Note that you also need to check if the year is a leap year or not. For example, if the user enters 2014, we need to calculate how many days from 1800 to 2013. Need a for loop and in the for loop you need to check if the year is a leap year. ii. Add the total days from the beginning of the given year up to the month. For example, if we are trying to print the calendar for the March 2014, then we need to add the total number of days in Jan and Feb to whatever we calculated in i. iii. Whatever you get from ii add 3 to it (January 1800 was on a Wednesday) iv. Calculate the remainder of iii divided by 7, this result will tell you that first days of month is Sun or Mon or Tue or Wed or Thu or Fri or Sat. 4. Determine the date for thanksgiving for November. 5. Now that you know the number of the days in the month and the day for the first day of the month you can print the calendar. 3. Now you can write a method that accepts the number of the days in the month and the first day of the month, then print the body a. 1. If the first day of the month is for example on a Saturday which is the 6th day of the week then you need to output 5 blanks . b. You start printing from 1 to the last day of the month. Add appropriate codes in the main method to give the user the option of displaying the calendar for the year or the month. Based on the users option display the result.

you can use this procedure
