PLEASE LOOK OVER THE WHOLE QUESTION ESPECIALLY THE SAMPLE OUTPUT AND THE SHELL.
Edit: When I post from word to chegg, it sometimes messes up the formating of the sample output, but it should give you a general idea what it looks like.
I have posted this question a few times already, but no one has done it like the instructions ask.
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.
Get the users input
a. Read the input(year)
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.
Print the month and the year
Print Sunday Monday Tuesday Wednesday Thursday Friday Saturday.
ii. Print the body for the month
Get the number of the days for each month of the year
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
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
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.
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.
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.
Determine the date for thanksgiving for November.
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.
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
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 .
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.
A program shell has been provided for you.
Here is a sample output

Here is the Shell to the program. It is incomplete and needs to be filled in. Using the Sample Output fill in the rest. Please do not just create just a regular calender by inputing the year. It needs to follow how the sample output looks like.
import java.util.Scanner; public class PrintCalenderShell { public static void main(String[] args) { Scanner kb = new Scanner(System.in); //prompt the user to enter the year boolean repeat = true; while (repeat)//repeat as long as the user wants to { //your code } } /*this method prints the body of the calender for the given month*/ public static void printMonth(int year, int month) { //call the method printTitle with the values year and month //call the method printMonthBody with the values year and month } /*this method prints the title of the days in each week(sunday Mon Tues Wed Thur Fir Sat)*/ public static void printMonthTitle(int year, int month) { //output the title for each month of the year } /*this method outputs the calender for each month of the year*/ public static void printMonthBody(int year, int month) { //call the method getStartDay to get the start day for each month of the year //call the method print to print the calender for the month and pass the first day of the month as the parameter } /*prints the calendar for the given month*/ public static void print(int startDay, int year, int month) { // call the method getNumberOfdaysInMonth to finde out the number of the days in the month //use a for loop to print spaces up to the start day for each month //use another for loop to print the rest of the days in the calender //if the month is November calculate the thanksgiving day and output } } /*this method calculates the date for thanksgiving, you need to use a switch statment.
