Thread: i dont know what to do to count all matching words

i have a bunch of string each in their own array element.

i put each array element into its own new array, the new array holds each word of the string.

i take the array holding individual words, and compare it to the array of strings with multiple words.

i want to count the number of times the word appears in the text file, in such a way that i can identify the array element that holds a string with multiple is where the word was counted in.

here is the text file article.txt;

Code:

The Lion and the Mouse

Once when a lion, the king of the jungle, was asleep, a little mouse began running up and down on him. 
This soon awakened the lion, who placed his huge paw on the mouse, and opened his big jaws to swallow him.

"Pardon, O King!" cried the little mouse. 
"Forgive me this time. 
I shall never repeat it and I shall never forget your kindness. 
And who knows, I may be able to do you a good turn one of these days!”

The lion was so tickled by the idea of the mouse being able to help him that he lifted his paw and let him go.

Sometime later, a few hunters captured the lion, and tied him to a tree. 
After that they went in search of a wagon, to take him to the zoo.

Just then the little mouse happened to pass by. 
On seeing the lion’s plight, he ran up to him and gnawed away the ropes that bound him, the king of the jungle.

"Was I not right?" said the little mouse, very happy to help the lion.

MORAL: Small acts of kindness will be rewarded greatly.

here is my code so far;

the problem function is "public void compare(string [] long_line, int counter)". im lost as to how to get the proper count of the word "the" right now i count it 21 times but its in the text file 22 times.
