import java.io.*;
import java.util.*;

public class Readscorecard {

private Scanner file;
private double TPar, TPlayer1, TPlayer2 , TPlayer3, TPlayer4;
private double Par, Player1, Player2, Player3, Player4, Sum;

public void scorecard(){

try{
file = new Scanner(new File("golfFile.txt"));
}
catch (Exception e){
System.out.println("you received an Error");
}
}

public void readgolffile(){
System.out.printf("%-10s %1s %12s %12s %12s\n", "Par", "Player 1", "Player 2", "Player 3", "Player 4\n");

while (file.hasNext()){
Par = file.nextDouble(); //Line 31

Player1 = file.nextDouble();

Player2 = file.nextDouble();

Player3 = file.nextDouble();

Player4 = file.nextDouble();

System.out.printf("%-10s %1s %12s %12s %12s\n", Par, Player1, Player2, Player3, Player4);

System.out.println("_________________________________________________");
