Assign scanned values from file to object's parameters?-CodePudding

I am scanning a file that has an athelete's name and his scores:

John Smith; 24; 14;
Adam West; 17; 9;

How can I separate these values? As in John Smith is the name, 24 is his A score, 14 is his B score? I'm thinking to create an "Athlete" object with such parameters, but I don't know how to 'assign' them.

My scan:

        File file = new File ("input.txt");
        Scanner scan = new Scanner(file);
        while(scan.hasNextLine()) {
            System.out.println(scan.nextLine());
        }

Based on how question was asked I assume that you start with Java (or programming).

Beginner approach would be to split each line:

  String line = scan.nextLine();
  String[] fields = line.split(";");
  String name = fields[0];
  String aScore = fields[1];
  String bScore = fields[2];

Then you can figure out the rest. Of course this code needs error handling, because there can be less (or even no semicolons).

In comercial environment instead of doing that on your own you'd be better off using one of available libraries that parse CSV-like files like Apache Commons CSV. Then you can define named headers and rely on external library to handle errors in input file for you.
