Description
The program begins by printing a short introduction. Then, the program prompts for a patient’s name, followed by the patient information that will be used to compute the priority score. The program uses this information to compute a score and determine the patient’s priority. This information is printed out, along with a brief recommendation based on the priority. The program then prints a thank you message and prompts for another patient name. This process continues until the word “quit” is typed as the name, at which point summary statistics for the day are printed.Specification
Program Behavior
You can see an example interaction with the program below (user
input is bold and underlined):
Hello! We value you and your time, so we will help
you prioritize which patients to see next!
Please answer the following questions about the next patient so
we can help you do your best work 🙂
Please enter the next patient’s name or “quit” to end the program.

Good job today!
The program begins by printing a short introduction. Then, the program prompts for a patient’s name,
followed by the patient information that will be used to compute the priority score (see below). The
program uses this information to compute a score and determine the patient’s priority. This
information is printed out, along with a brief recommendation based on the priority. The program
then prints a thank you message and prompts for another patient name. This process continues until
the word quit is typed as the name, at which point summary statistics for the day are printed (see the
Daily Statistics section below).
⌨️ User Input
You should use the Scanner class to read in all user input through the console. For numerical user
input, you should use the nextInt() or nextDouble() method. For all other user input, you should use the
next() method.
Be very careful NOT to use the Scanner’s nextLine() method! Some very unintuitive and tricky bugs arise when you mix
nextLine() and nextInt() calls on the same Scanner, so make sure to only use next() for non-numerical user input in this
assessment.
You may assume that all of the user’s answers will be a single token of the appropriate type. In
other words, where the program prompts for and expects an int input, you can assume that the user’s
answer will be an int. Similarly, where the program prompts for and expects a String response, you
can assume that the user’s answer will be a String, and where the program prompts for a double, the
user will enter a double.
Checking for Valid User Input
You may assume that the user enters reasonable or “valid” responses when prompted for each piece
of information, with two exceptions:
● You should verify that the user enters a 5-digit integer when prompted for the patient’s
zip code. The formula for calculating the patient score relies on the first and second digits of
the zip code, so we need to make sure that the user enters a valid zip code to factor it into the
formula appropriately.
● You should verify that the user enters an integer in the range 1-10 (inclusive) when
prompted for the patient’s pain level. The pain level of the patient directly affects the
calculated priority score, so you should ensure the entered pain level is within the appropriate
range.
If the user enters an invalid zip code, you should reprompt the user with the message “Invalid zip code,
enter valid zip code: ” until they enter a valid zip code. Similarly, if the user enters an invalid pain
level, you should reprompt the user with the message “Invalid pain level, enter valid pain level (1-10): ”
until they enter a valid pain level.
Priority Score
We use the information that the user inputs (“features”) to calculate a priority score for the patient.
The patient features used for the calculation are:
● age
● zip code
● whether this hospital is “in network”
○ an answer of y or yes indicates that the hospital is “in network” for the patient
○ any other response indicates that the hospital is not “in network” for the patient
● pain level
● temperature
Score Calculation
Each patient starts out with a base score of 100, which then is increased or decreased based on the
inputted information as follows:
● If the age of the patient is a child (younger than 12 years old) or a senior citizen (at least 75
years old), add 50 to their score.
● If the first digit of their zip code is the same as the first digit of the hospital’s zip code, add 25
to their score. If the second digit of their zip code also matches the second digit of the
hospital’s zip code, add another 15 to their score.
○ NOTE: If the first digit of each zip code doesn’t match, then it doesn’t matter whether
the second digits of each zip code match – no change should be made to the patient’s
priority score.
● If the hospital is “in-network” for the patient’s medical insurance, add 50 to their score.
● Take the patient’s reported pain level, multiply it by 10, and add it to their score.
● If the patient’s temperature is above 99.5 degrees Fahrenheit, add 8 to their score.
Hospital Zip Code
Your program should use a class constant to represent the hospital’s zip code, named HOSPITAL_ZIP.
The default hospital zip code will be 12345 (and this is what these sample logs use) but you should be
able to change the value stored in this class constant to another 5-digit value and have the rest of the
program operate seamlessly.
Make sure to correctly declare the class constant as public, static, and final!
️ Priority Determination
Once the priority score is determined, each patient is placed into one of three different priority groups
based on their score.
● High priority: Patients with scores that are greater than or equal to 333 are considered “high
priority”, and the following output should be printed.
We have determined this patient is high priority,
and it is advised to call an appropriate medical provider ASAP.
● Medium priority: Patients with scores greater than or equal to 168 but less than 333 are
considered “medium priority”, and the following output should be printed.
We have determined this patient is medium priority.
Please assign an appropriate medical provider to their case
and check back in with the patient’s condition in a little while.
● Low priority: Patients with scores less than 168 are considered “low priority”, and the
following output should be printed.
We have determined this patient is low priority.
Please put them on the waitlist for when a medical provider becomes available.
Daily Statistics
The program should continue to process patients until the user quits the program by entering quit
(exactly like this, all lowercase) when asked for the next patient’s name. Once the user does this, the
program should output some statistics about the patients that it evaluated that day. In particular, it
should print
● The total number of patients processed
● The priority score of the highest priority patient it processed
Program Structure
Your program should utilize methods, parameters, and returns to add a clear and understandable
structure to the code. In particular, your code should include at least the following 7 methods with
the indicated parameters and return values:
1. A method to print the program’s introduction message
○ no parameters
○ no return value
2. A method to get a patient’s name through user input
○ takes one Scanner parameter
○ returns the name read from input
3. A method to collect the required patient information (age, zip code, insurance information,
pain level, and temperature) and compute the priority score
○ takes one Scanner parameter
○ returns the computed score
4. A method to calculate the priority score of the patient (this method should be called in the
above method)
○ takes five parameters, once for each patient feature
○ returns the computed score
5. A method to print the patient’s priority
○ takes two parameters– the name and the score
○ no return value
6. A method to print out the overall statistics for the day
○ takes two parameters– the number of patients and the maximum score
○ no return value
7. A method to find out if the zip code has 5 digits (this is provided in your workspace)
With the exception of methods 4 and 7, all these methods should be called from main. Method 4 should be called from
method 3. Method 7 should be called where ever you check that the user input is valid.
You may include additional methods if you wish, but you must include these methods as defined.
(Naturally, your program will also include a main method.)
Along with the required methods above, you must have a loop in main which allows the program to
keep asking for new patient information until the user chooses to quit.
