emphasized textI am currently trying to run this code (with two different files). One file is just a dictionary of words and the other is just a file with some text. When I run this code, my code outputs the entire text of the file that is provided in getIncorrectWords. I know this is wrong since there are errors that this SpellChecker should be picking up (and only the incorrect words should be printed out). I went back to make some changes to my constructor and I cannot seem to find the error in my code. Can anyone provide some input as to what could be going wrong with my program and provide some hints or advice for how to fix it? For reference I am making a SpellChecker which stores a "dictionary" -some defined words, in a HashSet. I am supposed to parse through another file and check which words in it are not defined in the dictionary and store those in a List. This is done n my getIncorrectWords method. Finally I am providing suggestions for what words could have been meant in my getSuggestions method. The suggestions are found by the following:

Add One Character - Try adding a character at every point in the string and see if that creates a valid word.

Remove One Character - Try removing one character from any position and see if that creates a valid word.

Exchange Adjacent Characters - Try swapping two consecutive characters at any position in the string and see if that creates a valid word.

Thank you for the time and input!

This is my main class where I call the functions.

public class SpellCheckerTester {



    public static void main(String args) throws IOException {



        SpellChecker checker = new SpellChecker("words.txt");

        List<String> incorrectWords = checker.getIncorrectWords("test.txt");



        for (String word : incorrectWords) {

            List<String> suggestions = checker.getSuggestions(word);

            System.out.print(word + " - ");

            for (String suggestion : suggestions) {

                System.out.print(suggestion + " ");

            }

            System.out.println();

        }

    }

}
