Solved: Java: Error when reading a file

All,

I'm trying to read and output the contents of a file called credentials.txt. The code is below and attached is the error I'm getting.

package testingrandommethods;
import java.util.Scanner;
import java.io.*;

public class TestingRandomMethods {

public static void main(String[] args) throws IOException { //I had an error until I added "throws IOException" when trying to open the file.

FileInputStream fileByteStream = null;
Scanner credFile = null;
String credData = "";

//Attempt to open file
fileByteStream = new FileInputStream("credentials.txt");
credFile = new Scanner(fileByteStream); //credFile now contains what's in credentials.txt.
System.out.println("Reading and printing data.");
credData = credFile.next(); //credData now contains what's in credentials.txt as well. It allows me to read through the file.

while (credData.charAt(0)){
System.out.println(credData);

credData = credFile.next();
}
System.out.println(credData);

//Close the file
System.out.println("Closing the credential.txt file.");
fileByteStream.close();
return;
}

}
