This part of the homework requires you to submit a single java file, called Number DaysLeft This Year.java. Make a folder called homework3 inside of the cs110Submissions folder in your computer, and you can save and edit your code as you work on this programming assignment, but it is only the file that you upload to Canvas that will be scored. Always upload only *java files. For this programming task, you'll use conditional control statements (if, if-else, if-else-if, etc.), as well as the switch statement, that you learned about in Lecture 8. Your program will prompt the user to input the day (a number), month (a string), and year (a number). You can use the Scanner class, or the JOptionPane class, to receive input from the user. Using that information, your program will calculate the number of complete days that are remaining in the year specified by the user. For full credit, your program will need to consider whether the year supplied is a leap year, which is governed by the rules in Figure 1. Samples of code were also given in class. 1. 2. 3. 4. 5. If the year is evenly divisible by 4, go to step 2. Otherwise, go to step 5. If the year is evenly divisible by 100, go to step 3. Otherwise, go to step 4. If the year is evenly divisible by 400, go to step 4. Otherwise, go to step 5. The year is a leap year (it has 366 days). The year is not a leap year (it has 365 days). Figure 1 Use a switch statement to process the month (of type String) that is input by the user, and any combination of if, if-else, if-else-if, if-else-then, etc. conditional statements, to calculate the number of days left in a year. An example of a pseudo-code for the entire program is given to you in Figure 2. // declare variables dayOfMonth and year of type int CS110, Tatiana Harrison, CWU, HW 3: Conditionals, the switch constructor Page 1 of 3 // declare variable monthName of type String // set up scanner and ask user to provide month, day of month, and year // using nextLine() for monthName, and nextInt() methods for dayOfMonth and year // declare variable days Leftin Year of type int, and assign it the value 0 // declare variable isLeap Year of type boolean, and assign it the value false // Determine whether the year is a leap year, using the following rules: // 1. If the year is evenly divisible by 4, go to step 2. Otherwise, go to step 5. // 2. If the year is evenly divisible by 100, go to step 3. Otherwise, go to step 4. // 3. If the year is evenly divisible by 400, go to step 4. Otherwise, go to step 5 // 4. The year is a leap year (it has 366 days). // 5. The year is not a leap year (it has 365 days). // Use a switch statement to determine the number of full days left in the year. // For example, December has 31 days, so daysLeftinYear = 31 - dayOfMonth. // For November, there are 30 days +31 days in December, so if user inputs November, days LeftinYear = 61 - dayOfMonth. // You will need to look up the number of days in each month. // For February, IF it is a leap year, then daysLeftinYear = 335 - dayOfMonth, and if it is NOT a // leap year, then daysLeftinYear = 334 - dayOfMonth. // For January, if it is a leap year, then daysLeftinYear = 366 - dayOfMonth. // If it is not a leap year, then if user indicates January, then daysLeftinYear = 365 - dayOfMonth. // output the correct text, (don't forget plural vs singular), to indicate how many days there are left in the year. Figure 2 The partial code for the switch statement is shown in Figure 3. switch(monthName}{ case "December": // always has 31 days daysLeftln Year = 31; daysLeftln Year -= dayOfMonth; break; case "November": // always has 30 days daysLeftinYear = 61; daysLeftinYear - dayOfMonth; break; Figure 3 To test your code, be sure to use a variety of month/day/year combinations. Using the leap year algorithm in Figure 1, the year 2000 is a leap year, but the 1900 was not. Also, the year 2007 was not a leap year, but 2008 was. Use at least these four years, to test your program for days in months that were before the leap day, and after the leap day. Sample invocations are shown in Figure 4. Sample invocation 1 (2007 is NOT a leap year): What month is it? December What day of the month is it? 30 What year is it? 2007 There is 1 complete day left in the non-leap year 2007. Sample invocation 2 (2008 is a leap year, and date input is in January): What month is it? January What day of the month is it? 31 CS110, Tatiana Harrison, CWU, HW 3: Conditionals, the switch constructor Page 2 of 3 Page < 2 of 3 ZOOM + What year is it? 2008 There are 335 complete days left in the leap year 2008.
