Count characters in file

Question

I have created the below code to count the number of characters in a file. It compiles but does not run.
It gives me the following error:
Exception in thread "main" java.io.FileNotFoundException: Test.txt (The system cannot find the file specified)
     at java.io.FileInputStream.open(Native Method)
     at java.io.FileInputStream.<init>(FileInputStream.java:106)
     at java.util.Scanner.<init>(Scanner.java:636)
     at CountFIle.main(CountFIle.java:18)
   import java.util.Scanner;      
     import java.io.File;
    public class CountFIle
       public static void main(String args[]) throws Exception
         File file = new File("Test.txt");
         Scanner input = new Scanner(file);
         int charLength = 0;
         while (input.hasNext()) {
            charLength++;
         System.out.println(charLength);
   }Can anyone please help me with this error???

Answer 1

1) It's considered bad form to hijack an old dead thread. Better to start a new one and show a link to this if necessary.
2) You have to actually read the file within the loop. The scan2.hasNext( ) only checks to see if another token is available. Within the loop you need to take that token and consume it somehow. i.e.,
Scanner scan2 = new Scanner (inputFile);
String thisToken = "";
while (scan2.hasNext())
    thisToken = scan2.next();
    //chars++;
}Though if you really want to know lines, words, and chars, you will probably check for hasNextLine( ), read the line into a string, parse the string into tokens all the while counting lines, tokens (words), characters,....
