converting a string; keyboard entry in java

Question

I have this code for converting a markdown string to html:

public static String convert(String str) {
    if (str.equals("# "))
        return " ";

    if (str.matches("#+.+")) {
        int n = str.length() - str.replaceFirst("#+", "").length();
        return "<h" + n + ">" + str.substring(n) + "<h" + n + ">";
    }

    return str;
}

What I would like to know is how to get this class to get its string from keyboard entry?

You could use Scanner.nextLine():

String stringToConvert = new Scanner(System.in).nextLine();
System.out.println("Converted string is: " + convert(stringToConvert));

I write this inside of the convert method or in the main? – Arn0ld_t Oct 21 '12 at 21:49
You would put this in `main`. – Reimeus Oct 21 '12 at 21:51
and what do i do if i want my "program" to convert a document and return the solution in another one? – Arn0ld_t Oct 21 '12 at 22:03
You would have to write the returned string to file. See this [related post](http://stackoverflow.com/questions/1053467/how-do-i-save-a-string-to-a-text-file-using-java). – Reimeus Oct 21 '12 at 22:12

Just to keep it simple you can go by Console.readLine().

No, you defined a method, you must pass the return value from `readLine` to your `convert` method. – Jack Oct 21 '12 at 21:40
so in my main i could write a=console.readline() and then in convert(string a) ? – Arn0ld_t Oct 21 '12 at 21:41
