Question

Creating a calendar for a given year A shell for this assignment has been provided so that you can fill in the methods Homework 4 grading rubric 1. Output examples a. One Normal Year, 10% b. One Leap Year, 10% 2. Style Meaningful variable names, 10% b. Meaningful method names, 10 % c. Comments, Total: 10% . Do not comment every line. 5% . Comment non-obvious code. 5% a d. Indentation, 10% e. Block comment with name and hour, 5% 3. Calendar, a. Title includes Month and Year, 5% b. Correct number of days in month from method, 10 % c. Correct first day of the month, 5 % d. Method takes firstDay and MonthLength, 10% e. Padding, Total: 15% i. Month name is centered 5 % i. Spacing between day numbers changes, 10% 1. for example: "I" and "10" are padded to the same length f. Month starts at day 1,5% These must be demonstrated by the student o Can handle complex logic Can break logic into more simple subproblems o Use of while loops, and other ch5 tools o Use of modulus o Use of methods Return values captured and used. Writing methods o Student has learned good style Problem: Write a program that prints the calendar for a given year

Use Java please
