Creating Objects from input file - class

Question

I'm trying to somehow create objects by reading from a text file. However, I seem to be doing something wrong, and I can't put my finger on it.
Main:
import java.util.*;
import java.io.*;
public class Project2 {
public static void main(String[] args) throws IOException {
Scanner sc = new Scanner((new File("Project2DataFile.txt")));
sc.useDelimiter(",");
ArrayList<BaseballPlayer> myplayer = new ArrayList<BaseballPlayer>();
while (sc.hasNext()) {
String str = sc.nextLine();
for(int cnt = 0; cnt < 4; cnt++){
BaseballPlayer player = new BaseballPlayer();
if( player.batavg < 0 || player.batavg > 100 ){throw new IllegalArgumentException ("Illegal Batting Avg");}
player.pnumber = sc.nextInt();
player.lastname = sc.next();
player.firstname = sc.next();
player.batavg = sc.nextFloat();
}
continue;
}
System.out.println(myplayer);
}
Class:
public class BaseballPlayer {
public static int pnumber; // player number
public static String lastname; // player's last name
public static String firstname; // player's first name
public static float batavg; // player's batting average
}
And I might as well put the text file in there too:
48,deGrom,Jacob,.120
58,Mejia,Jenry,.140
49,Niese,Jon,.091
7,d'Arnaud,Travis,.324
21,Duda,Lucas,.237
4,Flores,Wilmner,.268
11,Tejada,Ruben,.345
5,Wright,David,.289
3,Granderson,Curtis,.327
12,Lagares,Juan,.298

Answer 1

It seems you are using static incorrectly. static is for members shared by all instances of a class, so you should not use it in BaseballPlayer. To fix the problem, you need to remove all statics in BaseballPlayer.
