Implement MyHashedSet and MyHashedMap as define in Java Collection Framework and Java Map.

Counting the Occurrences of Words in a Text

Write a program that counts the occurrences of words in a text and displays the words and their occurrences in ascending order of the words. Must use your implementation of MyHashedSet and MyHashedMap.

The program uses a hash map to store a pair consisting of a word and its count. For each word, check whether it is already a key in the map. If not, add the key and value 1 to the map. Otherwise, increase the value for the word (key) by 1 in the map. To sort the map, convert it to a tree map.

These are my codes so far

MyMap: https://pastebin.com/n341XuUd

MySet: https://pastebin.com/Q5p6hgJU

From the links above, MyHashedSet implements MySet and MyHashedMap implements MyMap

I am now stuck. I really tried to make a program "that counts the occurrences of words in a text and displays the words and their occurrences in ascending order of the words".This is what I have so far on the link.

When I tried running it, rather than using file.txt but using KeywordCounter.java, I got errors saying.

java.io.FileNotFoundException: KeywordCounter.java (The system cannot find the file specified)

at KeywordCounter.scanFile(KeywordCounter.java:35)

at KeywordCounter.main(KeywordCounter.java:89)

Is there any way the code KeywordCounter can be fixed?
