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;
}

}

No need to post a new question. This would have come out from your last one
You need to look at examples of using a Scanner.

while(credData.charAt(0))
Open in new window

won't compile because the method of String that you're calling returns char, not boolean. Unlike other languages, conversion to boolean is not possible

while(credFile.hasNext())

Open in new window

is the sort of thing you should be using
