What's the best way to determine the total number of words of a file in Java?

Question

What is the best way to find the total number of words in a text file in Java? I'm thinking Perl is the best on finding things such as this. If this is true then calling a Perl function from within Java would be the best? What would you have done in condition such as this? Any better ideas?

Answer 1

int count = 0;
Scanner sc = new Scanner(new File("my-text-file.txt")); 
while (sc.hasNext()) {
   ++count;
   sc.next();
}
