There are several steps needed to count the number of words.
You must find the first occurrence of the word and then you must advance past its location to find the next and do the same again to find the next and continue until you do not find any more.

Look at the methods in the String class to see which will look for a String/word and return its location in the String being searched.

There's also a method to split a String into an array of words. That could be useful - it's trivial to find the size of an array.

Not sure the OP is ready for regular expressions.
Words can have ending .,; and be in '"()s

Maybe I misread the requirement. I was thinking: how many times does the word "the" occur in a String.
If I missed the requirement then your solution would be the one to use.

Regex - maybe not - although this is the archetypal example for that method, so the necessary code is very easy to find.
I jumped to thinking the requirement was "words" as in "white-space delimited strings", but I have to agree that it can be read with a more english-language understanding of "word". An example of typical input and correct output would be useful.
