output giving null, methods not reading properly
Whenever I try to run the program, its giving me null for my scoresheet and 0 for my score. And my toString() is returing null but my System.out.println(l.getName()); and System.out.println(l.getGame()); are returning the proper strings. But i need to have my score and scoresheet to read properly. Thanks for the help.
Code:

int i = 0;
while(s.hasNextLine()){
pins[i] = s.nextInt();
i++;
System.out.println(pins[i]);
}
s.close();
}catch(Exception e){e.printStackTrace();}
}
