Code:

import java.io.*;

import java.util.Scanner;

class Main

{

publicstaticvoid main(String[] args)

{

Scanner fin;

String lineIn; // To store one line at a time from the file

String[] lineData; // To store an array of data from one line of the file

try

{

// Set up file input reader and open file:

fin = new Scanner(new File("EmploymentDataSF_2020.csv"));

// input the first (header) line from the file.

lineIn = fin.nextLine();

// split on commas, put individual values into lineData array:

lineData = lineIn.split(",");

// THIS IS JUST A DEMO EXAMPLE FOR YOU TO CHANGE:

System.out.println("The first column header is: " + lineData[0]);

System.out.println("The second column header is: " + lineData[1]);

}

catch(IOException e)

{ // handle file i/o errors:

System.out.println("Unable to open file: EmploymentDataSF_2020.csv");

System.out.println(e.getMessage());

return; // end the program

}

catch(Exception e)

{ // handle other errors:

System.out.println("The file EmploymentDataSF_2020.csv isn't in the right format:");

System.out.println(e.getMessage() + "\nOutput file is probably incomplete.");

}

Sample Outputs:

** When EmploymentDataSF_2020.csv is not in repl Files: **

Welcome to the Employment Data Analyzer.

Unable to open file: EmploymentDataSF_2020.csv

EmploymentDataSF_2020.csv (No such file or directory)

** When EmploymentDataSF_2020.csv has an incomplete line: **

Welcome to the Employment Data Analyzer.

Enter name of output file to create:

popularJobs.csv

The file EmploymentDataSF_2020.csv isn't in the right format:

5 values should be in each line, separated by commas.

Output file is probably incomplete.

** When EmploymentDataSF_2020.csv is complete: **

Welcome to the Employment Data Analyzer.

Enter name of output file to create:

trash/trash

Unable to open file: trash/trash

trash/trash (No such file or directory)

Enter name of output file to create:

popularJobs.csv

The most common computer occupation in SF is 'Software developers and software quality assurance analysts and testers', with a mean annual wage of $144,740

Data for occupations with more than 10,000 workers saved to popularJobs.csv
