To build a complete working Java program that offer practice with a more involved Java graphical user interface, object oriented programming with a data structure, and a large data file.

Overview & Instruction

Your workplace maintains several distribution centers around the U$.$S$.$ for critically$-$needed vaccines. Users of your application will be health officials for one county or municipality throughout the the country. Write a JavaFX application to manage these distribution requests. You should include a front$-$end user interface that allows a user to select a county from within a state. You will be using the standad U$.$S$.$ Government FIPS codes that are unique numerical identifiers for county. It is a five$-$digit number with the first two digits relating to the state and the remaining three defining the county with the sate. Your program should include a front$-$end interface that allows the user to enter county FIPS information for a target county. The desired mechanism for this data$-$entry is a bit unorthodox and should appear like the picture

The interface will include a drop$-$down list with all $50$ states. Selection of a

given state code will insert the state FIPS identifier into a label $($i$.$e$.$

selection of $"$MI$"$ will set $"26"$ into the label$).$ The remaining digits will be selected using buttons that behave similarly to a combination lock. Pressing $"+"$ will increment the digit and $""$ will decrement it$.$ Be sure the digits wrap $9->0$ or $0->9$ as needed. Finally, the "Order Vaccine" button will process the indicated FIPS code and report a summary via a JavaFX Alert box with calculations and information as indicated below. In addition to these interface components shown above, be sure add the following:

$$ Reset button to change state drop$-$down list to "unselected" and all subsequent digits to zero.

$$ Check box indicating whether or not a super$-$cold storage facility is available.

$$ Radio button set to indicate the level of readiness the county is for vaccinations:

$$ Phase $1$: Health care and essential workers

$$ Phase $2$: Citizens served in Phase $1$ plus senior citizens

$$ Phase $3$: All citizens

When the user keys in a FIPS code and selects the readiness radio button and optional checkbox, your program should capture the FIPS code and then execute the following actions:

$1.$ Validate the FIPS code. If invalid $($i$.$e$.$ not found$),$ provide a JavaFX Alert box warning and perform no further actions.

$2.$ If FIPS code is valid,

a$.$ Get the latitude and longitude for the county requested.

b$.$ Determine distances from vaccine distribution centers $($using provided class below$).$

c$.$ Formulate the summary of the vaccine order $($as specified below$)$

The following specifications are needed for the solution:

Vaccine distribution centers are located in

$$ Kalamazoo, MI $($Latitude $42\mathrm{.}21,$ Longitude $85\mathrm{.}56)$

$$ Olive Branch, MS $($Latitude $34\mathrm{.}98,$ Longitude $89\mathrm{.}78)$

Shipment center selection: The distribution center to use for the vaccine order is defined using these criteria:

$$ If you facility does not have super$-$cold refrigeration capacity, they must use the Mississippi center.

$$ If the facility does have refrigeration capacity, then the distribution center that is closest to the county will be used.

Vaccine count: The count of vaccines will be $0\mathrm{.}5\%$ of the population of the county if only health care workers are ready to be vaccinated, $1\mathrm{.}0\%$ if health care worker and seniors are ready, and $2\mathrm{.}0\%$ if the county is ready for all citizens. Regardless of these numbers, no shipment can be more than $10,000$ doses. Shipment time: If shipment is less than or equal to $500$ miles, then the shipping time is one day. If the istance is over $500$ miles but under $1000$ miles, then it is two days. For all other U$.$S$.$ locations $1000$ miles or more away from the distribution center, vaccine shipments will require three days.

Necessary data files include:

$$ County data file: fipsCountyPopLatLon.txt$.$ The format for this file is:

$\{$state$\},\{$FIPS$\_$code$\},\{$name$\},\{$population$\},\{$latitude$\},\{$longitude$\}$

And an example line of data includes:

MI$,26017,$Bay,$106832,43\mathrm{.}699711,-83\mathrm{.}978701$

$$ State info file: stateFIPScodes.txt$.$ The format for this file is:

$\{$state$\_$name$\},\{$state$\_$code$\},\{$FIPS$\_$prefix$\_$code$\},$Distance calculation: To calculate the distances, you will need to integrate $($and likely alter$)$ the greatcircle distance formula. This formula is provided and demonstrated for you in the following example:DistanceCalc.java. $($Note: Western Hemisphere longitudes are negative$).$

Output should be a basic JavaFX Alert box containing the following information:

$$ County name

$$ Distribution center to ship from

$$ Number of doses to ship

$$ Distance of shipment from distribution center to county

$$ Anticipated date of shipment

$($Note that this item requires access to the current date and then increments must be added to it$.)$

Your application should be object oriented containing:

$$ The main application GUI

$$ A class to manage one "county".

$$ At least one class that will act as a "data manager" for an array of county objects.
