I am attempting to write a program it Java, but I am running into difficulties. For some strange reason I cannot seem to read text from a file. Here is my code maybe someone else can see what I am doing wrong.


Code:
import java.util.*;
import java.io.*;

public class SetUp {
   public static void main(String[] args) throws FileNotFoundException {
  Scanner scan = new Scanner(new File("Questions"));
  Scanner keyboard = new Scanner(System.in);
  while (scan.hasNextLine()) {
     System.out.println(scan.nextLine());
     keyboard.nextLine();
  }
   }
}

I have a file called Questions that is located inside the same folder as the program. This is being done on a mac.
Edit:
I'm throwing in another stupid question as well.
Is there a way to make text inside a JButton See through?

I just tried your sample program on my computer (I also created a dummy Questions.txt file to read from), and it didn't work. However, I got it to work by adding a .txt extension to "Questions". The one other thing I changed is I removed the second Scanner object, since you really only need one Scanner object for reading in a file.

The 2nd object was for me to see the contents one at a time.

Code:
joe@NAVI ~/Desktop $ javac SetUp.java
joe@NAVI ~/Desktop $ echo "blah blah" >> "Questions"
joe@NAVI ~/Desktop $ cat Questions
blah blah
joe@NAVI ~/Desktop $ java SetUp
blah blah
joe@NAVI ~/Desktop $


Although it seems to hang at the end and I have to kill it, but it does read fine. Something is wrong with where you're putting the file or what you're calling it. I'd look at your code, but honestly I haven't used java in a few years, since it's absolutely worthless :P

But it seems to work for me.

I believe that my problem was that I was using eclipse. When I manually went into the terminal it seemed to work just fine. Thank you for all your help. I'm sorry that my responses are short, but I'm still learning dvorak and it takes awhile to type anything.
