Question

I got another nooby question to Java gurus

Basically what I want is:

1. Take word;
2. Transform it to arrayOfChar;
3. Hide it to following manner: _ _ _ _;

I could get to to second step, however when I try to hide word in underscores it shows as ____ rather than _ _ _ _.

Code for it:

//Randomly picks word from Array which played 
public String pickWord(){
    String guessWord = (wordsList[new Random().nextInt(wordsList.length)]);
    return guessWord;
}

//Hides picked word
public char[] setWord(){
    word = pickWord().toCharArray();
    for (int i = 0; i < Array.getLength (word); i++) {
        word[i] = '_';
    }
    return word;
}

Answer 1

You will need to allow for the spaces in your new char array:

    String testWord = "test";
    char[] word = new char[testWord.length() * 2];
    for (int i = 0; i < word.length; i+=2) {
        word[i] = '_';
        word[i + 1] = ' ';
    }
