A simple approach would be to add a boolean variable, inQuote, and use that
to track whether or not you're within a quoted phrase. So asy ou are
iterating through the characters and reach a quote you set inQuote <-
!inQuote, and when you reach a whitespace character you can use the value
of inQuote to decide whether to count the word.
What happens if the user has accidently only supplied one open quote and not
a closed quote? If I use your approach, which sounded good at first, I'd end
up not reading enough spaces therefore having too many words...
afterthought: but then I could set the boolean to look for a second
quotation mark, else count the spaces... yeah maybe your approach is good
afterall, i'll try it.

For anything more complicated you might want to look at regular
expressions.

What's the best way to write code that will count the spaces between each
word but not prases that are sourounded by double quotation marks eg.
there are 2 phrases in the example below making up a total of 6 words (6
spaces), but how can avoid counting the spaces in the phrases?:
walls, plumbing, "painting & decorating", decorating, "concrete mixing
truck", concreting, bricklayers
This is the code I have so far:
public static String wordCounter(String s, int numOfWords){
int wordCounter=0;
int numToReduce=0;
for (int index=0;index<s.length();index++) {
char c = s.charAt(index);
if (Character.isWhitespace(c)) {wordCounter++;} // Counts the
spaces.
}
if (wordCounter > numOfWords) {
numToReduce=wordCounter - numOfWords;
throw new NSValidation.ValidationException
("You are only allowed to enter "+numOfWords+" words, but you
have entered "+wordCounter+". <br />"+
"You'll need to delete any "+numToReduce+" of these words.");
}
return s;
}
