Well it was going to be used as part of an eye dropper tool. So the user can select the pixel and then re-draw it with the same color and alpha value. I can always change it to take a sub-image and then re-draw that image where the user selects, but that is more of a workaround to what i was wanting, but still it will work.

yea that was what i was afraid of. I wanted to pull out accurate information for each pixel, but sense the user can change the pixels alpha value, this creates the accuracy problem. The values are commonly only 1-5 off of the original color. I wish there was a way to be able to pull out exactly what was drawn to the image to begin with. The only way i can think of doing it is to log the colors themselves in an array but that's obviously going to lead to a bigger file size when i saved a serialized class with them all.

Just as an edit, i have played around with transparency a bit more in a professional image editing program. It would seem if i can get rid of the alpha value somehow the original RGB values would be restored. In an image editing program, i would just continue to draw the transparent pixel over and over again until it was solid. In my case however, i cannot just do:

BufferedImage drawOver = new BufferedImage(50,50,BufferedImage.TYPE_INT_ARGB);
        g = drawOver.getGraphics();
        color1 = new Color(img.getRGB(0, 0),true);
        g.setColor(color1);
        g.fillRect(0, 0, 50, 50);
        g.fillRect(0, 0, 50, 50);
        g.fillRect(0, 0, 50, 50);
        g.fillRect(0, 0, 50, 50);
        g.fillRect(0, 0, 50, 50);
        g.fillRect(0, 0, 50, 50);

to fix the issue. All this does is replace the old pixel with the new one, and doesn't actually re-draw the pixel over the first one. Is there a way for me to re-draw pixels instead of just replacing them?

I honestly don't think there is a drive letter at all. If there was it would show up on the file chooser. I don't think the devices work as such by using a drive letter (which blows my mind because i was under the impression that all devices were assigned a drive-letter).

It would be best to set the 'clearFields' as a public method. like:

   public void actionPerformed(ActionEvent e)
   {
      //Assigning data
      id = idField.getText();
      password = passwordField.getText();
      success = false;

      //Sequential search
      for(int i=0; i<6; i++)
      {
		  if((idArray[i].compareTo(id)==0) && (passwordArray[i].compareTo(password)==0))
		  success = true;
	  }

	  if(success)
	  {
		  headerLabel.setText("Login Successful");
		  clearField();
	  }//close if
	  else
	  {
		  repaint();
	  }//close action performed
       }

       public void clearFields()
       {
           idField.setText("")
           passwordField.setText("");
           idField.requestFocus();
       }

Edit: sorry it's a bit messy, but you should still get the idea from it

Well the first thing you might want to do is make the entire thing one string.

so adjust your code to:

]import java.util.Scanner;

public class ReadData {

    public static void main(String[] args) throws Exception {
        // Create a File instance
        java.io.File file = new java.io.File("scores.txt");

        // Create a Scanner for the file
        Scanner input = new Scanner(file);
        
        // Create the Content String        
        String fileContent = "";

        // Read data from a file
        while (input.hasNext()) {
            fileContent += input.next() + " ";
        }
        // Close the file
        input.close();

That should get all of the files data into one solid string. The next thing we need to do is split the string into a character array:

char[] charArr = fileContent.toCharArray();

Now we need to loop through every character and look for 'a' 'e' 'i' 'o' 'u' and 'y' <- If you wish to use Y as a vowel.

int counter = 0;
for(char c : charArr)
{
     if(c == 'a' || c == 'e' || c == 'i' || c == 'o' || c == 'u' || c == 'y')
          counter++;
}
System.out.println("Number of Vowels: " + counter);

And that should be all there is to it! the final code should look like:

import java.util.Scanner;

public class ReadData {

    public static void main(String[] args) throws Exception {
        // Create a File instance
        java.io.File file = new java.io.File("scores.txt");

        // Create a Scanner for the file
        Scanner input = new Scanner(file);
        
        // Create the Content String        
        String fileContent = "";

        // Read data from a file
        while (input.hasNext()) {
            fileContent += input.next() + " ";
        }
        // Close the file
        input.close();

        //Split the string into a character array
        char[] charArr = fileContent.toCharArray();

        //loop through every character to find the vowels
        int counter = 0;
        for(char c : charArr)
        {
              if(c == 'a' || c == 'e' || c == 'i' || c == 'o' || c == 'u' || c == 'y')
                   counter++;
        }
       
        //Tell the user the number of vowels
        System.out.println("Number of Vowels: " + counter);
