I'm trying to read all integers from a file into an ArrayList in the @BeforeClass of a java JUnit test. For testing purposes, I am then simply trying to print all values of the arraylist to the screen. Nothing is being output however. Any input would be greatly appreciated.

```
public class CalcAverageTest
{

static List<Integer> intList = new ArrayList<Integer>();

@BeforeClass
public static void testPrep() {
    try {
        Scanner scanner = new Scanner(new File("gradebook.txt"));
        while (scanner.hasNextInt()) {
            intList.add(scanner.nextInt());

        }
        for (int i=0;i<intList.size();i++) {
            System.out.println(intList.get(i));
        }
    } catch (IOException e) {
        e.printStackTrace();   
    } catch (NumberFormatException ex) {
        ex.printStackTrace();
    }            
 }
}

```
