Issue With Finding Total Number of Blank Spaces in File

[Cod]

The goal of my assignment is to count the number of characters (w/o spaces and returns), words, and lines of a text document. The document is read-in and analyzed from there. I've got the reading in of the file working as well as the line counter; however, I've run into significant troubles with counting the characters. I can obtain the total number of characters, but I need to get a number without counting the spaces and returns. Here is what I've got thus far...

import java.io.*;

public class Counter {
  public static void main(String[] args) throws IOException {
    
    BufferedReader br = new BufferedReader (new InputStreamReader(System.in));
    
    // Read in all variables
    String document;
    long characterCount = 0;
    int spaces = 0;
    int wordCount = 0;
    int lineCount = 0;

      // Ask user to enter document title with extenstion. Then convert file for finding required information.
      System.out.println("Please enter the file name with extension: ");
      document = br.readLine();
      File file = new File(document);
      FileReader fr = new FileReader(file);
      
[COLOR="Red"]      // Find total number of characters within document
      characterCount = file.length();
      for (int i = 0; i < characterCount; i++) {
        if (document.charAt(i) == ' '); {
          spaces++;
        }
      }[/COLOR]

      characterCount = (characterCount - spaces);
      

      // Find total number of words within document

      
      // Find total number of lines within document
      LineNumberReader lnr = new LineNumberReader(fr);
      while (lnr.readLine() != null) {
        lineCount++;
      }
      
      // Print output of require information
      System.out.println("Number of characters in document: " + characterCount);
      System.out.println("Number of words in document: " + wordCount);
      System.out.println("Number of lines in document: " + lineCount);
    
  }
}

As far as the error message is concerned, it pertains to the portion of the code in red and reads:

[I]java.lang.StringIndexOutOfBoundsException: String index out of range: 8
	at java.lang.String.charAt(Unknown Source)
	at Counter.main(Counter.java:24)[/I]

Any guidance would be greatly appreciated.

document is the file name. It's not all the text in the file. You're going to need to analyze each line one at a time as you read it in.

That make sense Fubarable, weird I didn't catch that. Thanks for pointint me in the right direction. Just got the program figured out this morning and everything is working smoothly.

Thanks again.
