Word occurrences counter - Java example

The program counts the number of occurrences of a word in a given string. It trims the string to remove the leading and trailing spaces. Then it counts the target word at the beginning and at the end, if any. Then it counts the target words surrounded by spaces.

You'll learn most by trying my code while watching the video.
