streams!?!

[marky123]

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 -

public int countChars(InputStream is) throws IOException
{
   int count = 0;
   BufferedInputStream bis = new BufferedInputStream(is);
   while(bis.read() != -1) 
{
      count++;
   }
   return count;
}

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.
