import java.util.Scanner;

public class BowlerReader {

   private static final String FILE_NAME = \"bowler.txt\";

   public static void main(String[] args) throws IOException {

       System.out.println(\"Reading Data from file\");

       Scanner fileReader = new Scanner(new File(FILE_NAME));

       System.out.printf(\"%-20s%-10s%-10s%-10s%-10s\n\", \"Sample Data\", \"Game 1\", \"Game 2\", \"Game 3\", \"Average\");
       int bowler = 1;
       while (fileReader.hasNext()) {
           //reading scores for a bowler
           int s1=fileReader.nextInt();
           int s2=fileReader.nextInt();
           int s3=fileReader.nextInt();

           double average = s1+s2+s3;
           average =average/ 3.0;
           System.out.printf(\"%-20s%-10s%-10s%-10s%-10.2f\n\", \"Bowler \" + bowler, s1,s2,s3, average);
           bowler += 1;
       }
       fileReader.close();
