Question 4: Write a method called wordCount that accepts a String as its parameter and returns the number of words in the String. A word will be considered a sequence of one or more non-space characters (any character other than). You should not use Java's split() method. Note: you need to be careful with whitespace at the beginning and end of the string and be careful if there are multiple space characters in between words. This method should return an int. System.out.print(wordCount("hello")); System.out.print(wordCount("how are you?")); 1 3 System.out.print(wordCount()); 0
