Assignment Objectives
By the end of this assignment you should be able to design, code, run and test original Java programs featuring
if-statements, string manipulation and basic output formatting.
Part I: Time Flies When You’re Having Fun (3 points)
Filename(s):
PalindromicDate.java
Write a program that prompts the user to enter,
in this order
, (i) a month (which could be in mixed upper-
case/lowercase), (ii) a day and (iii) a four-digit year. Then, the program prints the date in a format
MM/DD/YY
,
with exactly two digits each for the month, day and year. It also prints whether the reformatted date is a palin-
drome.

Note:
Your program must check for bad input, such as an invalid month name, invalid day of the month, or
invalid year (less than 1). In such cases, print only the error message “Bad input.” and produce no other output.
Your program must handle leap years correctly.
Below are sample runs of the program.
±
Note:
You must use these prompts and output messages exactly as written. The grading system will be looking
for this wording.
Enter month: FEBruary
←

Enter day: 18
←
-
Enter year: 1979
←
-
Reformatted date: 02/18/79
Palindrome? no
Enter month: ocTobEr

Reformatted date: 10/11/01
Palindrome? yes
Enter month: APRIL

Bad input.
Part II: What A View! Wait, What’s That Smell? (3 points)
Filename(s):
StonyBrookResort.java
The Stony Brook Resort and Manure Depot offers a vacation package as follows:
•
The regular price for each adult is $125 per day. However, any days beyond the fifth day that an adult stays
are 25% off the regular price.
•
The price for each child is $75 per day regardless of how many days a group stays.
•
A $150 discount is given if the group’s stay begins on a Monday and lasts no more than 4 days (including
Monday itself).
•
A service charge of 5% of the original, non-discounted cost is applied for groups of 6 or more.
Write a program that prompts for,
in this order
, (i) the number of adults, (ii) the number of children, (iii) the
length of the vacation in days, and (iv) the day of the week that the vacation begins (which might be given in
mixed uppercase/lowercase).
Then, print the following values – again,
in this order
– formatted as dollar amounts with two digits after the
decimal point for cents: (i) the total before any discounts have been applied, (ii) discounts (if any), (iii) service
charges (if any), and (iv) the grand total.
