How to hide string with stars?

i have to prompt the user for a word and then print the word with stars. I know the process of asking the user for the word. Im not sure how to replace the characters with star. I know theres the .replaceAll method but I dont want to use that

I think that to use char array instead of String[] could simplify @VEdward's code. An char array can be easily assembled into String without writing a for loop. Scanner inp = new Scanner(System.in); String inStr = inp.next(); char[] inWordChars = inStr.toCharArray(); for (int i = 0; i < inWordChars.length; i++) { inWordChars[i] = '*'; } String outputStr = new String(inWordChars); System.out.println(outputStr);

Which do you want to hide, entire word or only specific characters?

ok, concatenate stars for [word length] times by for loop. instant example: public static String hide(String word) { String stars = ""; for (int i = 0; i < word.length(); i++) { stars += '*'; } return stars; }

Scanner inp = new Scanner(System.in); String inStr = inp.next(); //the word input by user //create array of size same as length of word String[] inWordChars = new String[inStr.length()]; //now split the string it will give array inWordChars = inStr.split(""); //replace all(or the ones you want) with stars for(int i=0; i<inWordChars.length;i++){ //replace each character to star inWordChars[i] = "*"; } //now we will join all characters //create a blank string String outputStr = ""; //add all members to string using for loop for(int j=0; j<inWordChars.length;j++){ outputStr += inWordChars[j]; } //at last print it to screen System.out.print(outputStr);
