Question

Hey I'm writting a code to count the numbers of letters and chacters in a sentence I type into an input box. My question is in order to count the letters and the spaces in between the letters what would I use to symbolize the spaces like I know how to count the letters but what would I use to count the spaces in between the words?

Take a look at the Character class. It has some handy categorization methodsyou can use: http://java.sun.com/javase/6/docs/api/java/lang/Character.html

> int spaces = words.length -1;

If you do this with sentence = "hello world " (note trailing space), spaces is still 1!

From the API for split:

Trailing empty strings are therefore not included in the resulting array.
