Homework 1
Getting Acquainted with Java

Due: Tuesday, March 24 at 5pm

• 4 Thursday
• 5 Friday
• 6 Saturday

Assumptions, Restrictions, and Hints

• Your program should be well-structured. Use loops intelligently. If you find yourself writing the same calculation over and over for each month of the year, for example, you should ask yourself if that calculation should be part of a loop. (Hint: each month of the year should be processed in an identical way. In fact, the only differences between one month and another is the name of the month and the number of days in the month. Your program should consist of a main processing loop that runs 12 times, once for each month in the year. Within the main processing loop, use a switch statement or a set of if statements to display the name of the month (and the year) and to set the number of days in the month. Nothing else needs to be done in your conditional statement.)

• You may not use arrays or ArrayLists in the solution for this program.

• You may define methods other than main() in your solution, but you are not required to do so.

• Make sure your program handles leap years correctly (look online to see how to determine if a given year is a leap year).

• Hint: after displaying a Saturday date, the program needs to move to the next output line. The program can determine when to do this using the current day of the month and the current day code (the day code is a number 0 - 6 representing which day of the week the first day of the month falls on...see sample execution below).

• Hint: after displaying all the days in one month, the program needs to calculate a day code for the next month. The program can determine the new day code using the current day code and the number of days in the current month.

  Sample Execution

  MONTHLY CALENDAR PROGRAM
  
  This program displays a calendar.  You need to provide the year, and the
  day of the week on which January 1 falls.
  
  Enter the year for which you would like a calendar:  2015
  
  Enter the code number for the day of the week on which January 1 falls:
  0- Sun  1- Mon  2- Tue  3- Wed  4- Thu  5- Fri  6- Sat
  Enter the day code now:  4

  (output continues for all 12 months)

  Deliverables

  Export your Eclipse project to a zip file and submit the zip file via web-based turnin. To export a project, go to File | Export… and choose Archive File from the General folder. Check off the entire project in the top left window and make sure the format is .zip and not .tar. Finally, give the archive file a name and click finish.

  The name of the turnin project is Homework 1.

  Programs submitted after 5pm on March 24 will be tagged as late, and will be subject to the late homework policy.

  Grading

  For Homework 1, we will provide the grade sheet that will be used when grading the assignment. Your program must compile without errors in order to receive any credit. It is suggested that before you submit your program, you should compile it one more time to make sure that it compiles correctly.
