Please design code for this assignment in Java. They have some code in them, you just need to make new code for each part that shows " // TODO: implement this ". There are 4 parts that is needed to do it. Thanks.

* Part 2: Implement this method.- * Load words from a file. Each line of the file contains a ward followed by one or more spaces followed * by a number whose value is higher for words that are more 'frequently occurring' than others. * Loaded words should have a frequency value in the range [minfreg, maxfreg]. However, at times, these * Limits should be ignored (see comments below). Note that the words in the file may be many lengths * (e.g., 3-10 characters). Onzy words of the specified length should be loaded. * Hint: use a Scanner instance to read in the file and look for the next string or Long value. * the following pattern will be useful i) * Scanner scan = new Scanner( new File (filenm)); * The line above creates a Scanner from a File with the filename stored in the variable filenm * Use the scanner's . hasNext() method to test if there are more lines to read. * Use the scanner's . next() method to grab the next String token (word). * The scanner's . nextlong() method wilz grab the next token as a number (use this to read the frequency). * For each line, you will want to call scan.next() and scan. nextlong() to read the data * identifying a ward and its relative frequency. * Words of the specified length should be added into the knownWords list if their frequencies * are the in the range specified. * Hint: somewhere around 10-20 lines is probably appropriate here unless you have a lot of comments * aparam filenm - the file name to load from * Qparam length - the length of words we want to load (e.g., 5 to load 5 character words) * aparam minfreg - the minimum allowable frequency for a loaded word * Qaparam maxfreg - the maximum allawable freguenct for a loaded word; indicates no maximum 1 usage: public void LoadWords(String filenm, int length, Long minfreg, Long maxfreg) throws I0Exception \{ // TODO: implement this return; /** * _Part 3: Implement this method.- * * Obtain a list of known words. This method creates a new copy of the known words list. * Here, you simply need to copy the knownords list and return that copy. * * Qreturn a new copy of list of known words. */ no usages public Arraylist getKnownWords() \{ \} I/ TOD0: implement this 1+4 * Part 4: Implement this Constructor.- * Given a guess and the secret word, provide a hint. * The Hint should follow these guidelines: * - the Hint should not store any knowledge of the secret word itself. * - conrectlyplaced should have a length equal to the length of the secret word * - Incorrectlyplaced should have a length equal to the length of the secret word * - notInPuzzle should hove a length less than or equal to the length of the secret word/guess. * A character in the guess that is bath the correct letter, and in the correct location in the word * Wilz appear in that location in the correctlyplaced String. Characters in the guess that are not * correctly placed will appear as the chap: I. in the correctlyplaced String. * Thus, for a guess "skate" and a secret word "score", the correctlyplaced will be: "s-.e" * A character in the guess that is the correct letter, but not in the correct location in the word * will appear in the same location as the guess when placed in the incorrectedplaced string. * Note that duplicate characters are a bit tricky, they must be examined for correctly placed characters * before incorrectly placed ones. * Thus, for a guess "scoop" and a seeret word "poafs", the corpectlyplaced string is: "zo-." and * incorrectlypzaced String is: "s--op" * Note that the first ' 0 ' is correctly placed, thus it must be the second 'o' that is incorrectly placed. * It is incorrect to say that the first 'o' is incorrectzy placed, as it is incorrect to say that * both 'o's are incorrectly placed. * Characters that are in the guess and are neither carrectly placed nop incorpectly placed should be * added to the notinPuzzle String. Thus, the length af the notinPuzzle String will never be greater * than the length of the secret word, or the guess. * * Gparam guess 1 usage public Hint(String guess, String secretWord) \{ // TODO: implement this \}
