Question

Create a JavaFX GUI program that allows a user to input the name of a state and display the state capital and population for that state.

When the program starts, it should first

READ and load the data
Open the data file (download attached file) and read the data. Create a StateCapital object for each capital and add it to a Map. Close the data file.

You will need to create a class called StateCapital consisting of the following data
- city
- state
- population

Include a constructor, accessor and mutator methods for each data members

Override the toString method.

here is everything in the txtfile witch is the picture

java.io.FileNotFoundException: state_capitals.txt (The system cannot find the file specified)

at java.io.FileInputStream.open0(Native Method)

at java.io.FileInputStream.open(Unknown Source)

at java.io.FileInputStream.<init>(Unknown Source)

at java.util.Scanner.<init>(Unknown Source)

at application.Main.readDataFromFile(Main.java:20)

at application.Main.<init>(Main.java:14)

at application.Main.main(Main.java:41)

Enter a state name: Indiana

State not found!

#include <iostream>
#include "quadraticExpression.h"

void evaluateExpression (const quadraticExpression &);
int main()

quadraticExpression q[6] = { quadraticExpression (2.1, 3, -7),

return EXIT_SUCCESS;
