Cracking Wordle Puzzles with Java

Are you tired of manually trying to solve Wordle puzzles? Well, with the power of Java, you can build your very own Wordle solver that can quickly and efficiently solve these puzzles for you. In this article, we will guide you through the process of building a smart Wordle solver with Java, step-by-step.

Introduction to Wordle

Before we dive into building our solver, let’s first understand what Wordle is. Wordle is a word-guessing game where the player has to guess a five-letter word within six attempts. For every guess, the game will provide feedback on how many letters are correct and how many of them are in the correct position. The game is challenging, but with a smart solver, we can solve it in no time.

Building the Solver

To build our solver, we will be using Java. We will first write a program that will read in a list of five-letter words from a text file. We will then loop through this list of words and compare each word with the given word, using the feedback we receive from the game to eliminate words that do not match. We will then repeat this process until we find the correct word.

Reading in the List of Words

The first step is to read in a list of five-letter words from a text file. We can use the following code to read in the words:

vbnetCopy codeList<String> words = Files.readAllLines(Paths.get("words.txt"));

Comparing Words

Next, we need to compare each word with the given word and eliminate words that do not match. We can use the following code to do this:

for (String word : words) {
    int[] feedback = getFeedback(word, givenWord);
    if (Arrays.equals(feedback, givenFeedback)) {
        matchingWords.add(word);
    }
}

Here, getFeedback() is a method that takes in two words and returns the feedback for the given word, and givenFeedback is the feedback we receive from the game for our guess. The matchingWords list will contain all the words that match the given feedback.

Finding the Correct Word

Once we have a list of matching words, we can repeat the process of comparing words and eliminating non-matching words until we find the correct word. We can use the following code to do this:

String guess = matchingWords.get(0);
while (!guess.equals(givenWord)) {
    matchingWords.removeIf(word -> !Arrays.equals(getFeedback(word, guess), givenFeedback));
    guess = matchingWords.get(0);
}

This code will loop through the list of matching words, eliminating non-matching words until we find the correct word.

Conclusion

In this article, we have shown you how to build a smart Wordle solver with Java. With this solver, you can quickly and efficiently solve Wordle puzzles and impress your friends with your word-guessing skills. Remember to keep practicing and refining your solver to make it even smarter.
