    copied!<p>I am writing a method to search through a dicitionary to find multiple words of the same length that contain the same letter at a set point. I.e. All words of length 5 that have b as their second letter. </p> <p>I'm writing this method by TDD is eclipse and so far my method is as follows:</p> <pre><code> private OpenQueue openQueue = new OpenQueue(); private boolean value; private int lengthOfWord, numberFound; private File inFile = new File("src/src/WordList"); //This is a text file public Search(int length) { this.lengthOfWord = length; } public boolean examine2(int crossingPoint, char letter) { try { Scanner input = new Scanner(inFile); while (input.hasNextLine()) { //while there are words left to be read String word = input.nextLine(); if(word.length() == lengthOfWord) { //if the word is of the right length while(word.charAt(crossingPoint-1) == letter){ numberFound = numberFound + 1; //number of solutions is increased by one openQueue.add(word);//word is added to the open queue value = true; //value is true when at least one solution has been found } } } } catch (FileNotFoundException e) { System.out.println("They File was not Found"); e.printStackTrace(); } System.out.println(numberFound); //returns number of words found return value; //should return true if there is at least one word } </code></pre> <p>For my test I trying to find all five letter words that have a second letter b and there are several words that fit this as I've checked manually. However when I run JUnit it says that it expected true but it was false.</p> <p>The code runs up to but not past the while(word.charAt(crossingPoint-1) == letter) loop, as previously I added in System.out.println("Here") before this loop to check were the code runs until. </p> <p>I'm not sure how to fix this in order for the code to run without the test failing. Thanks for your help. </p>
