write a class called FileParse.java that will go through a file and and essentially parse that file. The FileParse class should contain the following methods:

public static int countWords(String fileName, String word)

This method goes through a file and finds occurrences of the given word and keeps track of the number of times the word appears in the file.

Then the method will print out a message displaying the result.

Total number of occurrences: 15

Finally the method returns the number of occurrences as an int variable.

For the purposes of this homework you are safe to assume there is only one occurrence of the word per line.

public static boolean deleteLine(String fileName, int lineNum)

A method that goes through a file and deletes a particular line on the file where the line number is given .

Once deletion is completed, the following message is displayed on the console:

Line deleted!

If the line number does not exist, you will print

Line not found

Return true if the deletion was a success, false otherwise.

public static int refactor(String fileName, String original, String replace)

A method that goes through the file and replaces a word with a different word that was given to you.

Once the replacement is done, a message in following format is displayed on the console showing how many words were replaced:

Number of words replaced: 15

If no words were found, print

No words found

Return the number of words replaced as an int variable.
