streams!?!

this particular question is givin me a headache, can any1 help???

Using the countChars() method from the previous answer, write a method called fileSize() declared as follows:

public int fileSize (String name) {
...
}

which counts the number of characters in the file whose name is supplied as the "name" parameter. This method should return the number of characters in the file, or -1 if an IOException occurs.
Insert the code for your method in the space below:

Previous answer -
Expand|Select|Wrap|Line Numbers
  1. public int countChars(InputStream is) throws IOException
  2. {
  3.    int count = 0;
  4.    BufferedInputStream bis = new BufferedInputStream(is);
  5.    while(bis.read() != -1) 
  6. {
  7.       count++;
  8.    }
  9.    return count;
  10. }

So basically you have to create an InputStream from a file name, right?
Have a look at the FileInputStream class for that.

kind regards,

Jos

ps. don't forget to close the InputStreams where needed.
