copied!<p>Hey Jordan, your first attempt looks very good! You only need some more logic inside the while loop to read guesses and replace "*"s with correct guesses. And I would advise you to store the obfuscated word ("*****...") in a string also instead of just printing it out, will be handy later on..</p> <p>Judging by your code you don't need any help on user input, your only problem is correct replacing of stars with right guesses, lets get to it:</p> <pre><code>String secret; //read in secret string String displaySecret; //generate as many "*"s as secret is long and store them in displaySecret </code></pre> <p>Now the cool thing is this:</p> <blockquote> <p>...no repeated letters...</p> </blockquote> <p>which will make your assignment much easier! Look at the documentation of the String class provided by Williwaw. There you'll find two methods with which will lead to the solution:</p> <ul> <li>One method finds the first occurrence of a character inside a string and outputs its position. And since you don't accept duplicate letters, that'll also be the only occurrence.</li> <li>The other method can replace the character at a given position inside a string with another character.</li> </ul> <p>I think from that you'll find the solution easily. Feel free to ask further questions in the comments!</p> <p><strong>EDIT: Some more help</strong><br/></p> <pre><code>String secret = "example-text"; String displaySecret = ""; for (int i = 0; i < secret.length(); i++) displaySecret += "*"; char guess; //read in a guess int position = secret.indexOf(guess); //now position contains the index of guess inside secret, or //-1 if the guess was wrong String newDisplaySecret = ""; for (int i = 0; i < secret.length(); i++) if (i == position) newDisplaySecret += secret.charAt(i); //newly guessed character else newDisplaySecret += displaySecret.charAt(i); //old state displaySecret = new String(newDisplaySecret); </code></pre> <p>Damn I was sure there was some kind of setCharAt(int) method.. the loop does the job.</p>
