Java Question

Question

In Python I used this method for the basis of my Hangman game

letters=["A","B","C"]
word="CAT"
blanks="-"*len(word)

for i in range(len(word)):
if word[i] in letters:
blanks=blanks[:i] + word[i] + blanks[i+1:]

If the letter in word is in the list of guessed letters, it rebuilds the word blanks, inserting The letters where they belong.

My question is how can I rebuild a string in this manner using Java?

Answer 1

I am a nooby at Python so hopefully I'm on the right track with what you want here, but..:

You can use a StringBuilder to remove characters. It's a mutable String.
It may look something like this:

StringBuilder word = new StringBuilder("kitty");
// example stuff
char guess = 'k';
int index;

while((index = word.indexOf(guess)) != -1)
{// gets all repeated letters

// add guess to blanks
blanks[index] = guess;

word.deleteCharAt(index);
// remove guess from word
}

Or, use substring on a string to create a new string that does not include the removed character you wanted.

Or a for loop like this:
String word = "kitty";
char guess = 'k';

String newString = "";
for(int i = 0; i < word.length(); i++)
if(guess != word.charAt(i))
newString += word.charAt(i);

Awesome! Your final example should work perfectly... Thank You! That is exactly what I wasn't finding on Google. I was probably wording it poorly lol
