Displaying the length of a word using dashes

Question

So I get a random word from a website and use the length() method to obtain how many letters are in the word. Now I want to display these as dashes (-). For example, say the word is "dogs". The length method will return 4. Now I want to convert that into ----. Is there any way in java to say in - the number representing the length of the word?

you have to parse the html in java and search check this answer http://stackoverflow.com/questions/9664778/parsing-html-in-java?answertab=votes#tab-top — Jorge, Mar 06 '14 at 17:25

The simplest would probably be to use a regex:

String dashes = input.replaceAll(".", "-");

StringBuilder str = new StringBuilder();
for (int i = 0; i < word.length(); i++) {
    str.append("-");
}
System.out.println(str.toString());
