BJP4 Exercise 4.18: wordCount

Language/Type: Java if/else method basics return Strings
Author: Will Beebe (on 2016/09/08)

Write a method called wordCount that accepts a String as its parameter and returns the number of words in the String. A word is a sequence of one or more nonspace characters (any character other than ' '). For example, the call wordCount("hello") should return 1, the call wordCount("how are you?") should return 3, the call wordCount(" this     string has     wide       spaces ") should return 5, and the call wordCount(" ") should return 0.
