Having a problem figuring out where my errors are. The code is not running how I need it to so I added a few print statements to help me figure it out but to no avail. Any help would be greatly appreciated.

import java.io.File; import java.util.Scanner; import java.io.FileWriter; import java.io.IOException;

public class Main { public static void main(String[] args) { if(args.length != 1) { System.out.println("Usage: java Main "); return; } String inputFileName = args[0]; PersonSet orderedSet = new PersonOrderedSet(); PersonSet imperialSet = new PersonImperialSet(); try(Scanner sc = new Scanner(new File(inputFileName))) { if(sc.hasNextLine() && sc.nextLine().startsWith("Name\tHeight (cm)\t\tWeight (kg)")) { while(sc.hasNextLine()) { String line = sc.nextLine(); System.out.println("Line:" + line); String[] parts = line.split("\t"); if(parts.length == 3) { String name = parts[0]; double height; double weight; try { height = Double.parseDouble(parts[1]); weight = Double.parseDouble(parts[2]); Person person = new Person(name, height, weight); orderedSet.add(person); imperialSet.add(person); } catch (NumberFormatException e) { // skip this line } } } } } catch (IOException e) { System.out.println("An error occurred while reading the file."); e.printStackTrace(); return; } try(FileWriter writer = new FileWriter("hr_ordered_set_output.txt")) //write ordered set to file { writer.write("Name\tHeight (cm)\t\tHeight (kg) "); writer.write(orderedSet.toText()); } catch(IOException e) { System.out.println("An error occured while writing the ordered set output file."); e.printStackTrace(); return; } try(FileWriter writer = new FileWriter("hr_imperial_set_output.txt")) //write imperial set to file { writer.write("Name\tHeight (in)\t\tWeight (lb) "); writer.write(imperialSet.toText()); } catch(IOException e) { System.out.println("An error occured while writing the imperial set output file."); e.printStackTrace(); return; }

// Output the ordered data and the imperial data to the screen/console, nicely formatted System.out.println("Ordered data:"); System.out.println("Name Height (cm) Weight (kg)"); System.out.println("-------------------------------------------"); System.out.print(orderedSet.toString()); System.out.println("Imperial data:"); System.out.println("Name Height (in) Weight (lb)"); System.out.println("------------------------------------------"); System.out.print(imperialSet.toString()); }

}
