    Default replacing characters???

    I'm supposed to write a program that replaces all vowels in a word with * but i can't get it right! the most i can do is replace one vowel with teh code:

    Java Code:
    import java.util.Scanner;
    public class constanita {
    	public static void main (String[]args){
    		Scanner kbd = new Scanner(;
    		System.out.println("enter a word");
    		String x =;;
    		String noVowels = x.replace("a", "*"); 
    and whenever i try something like

    String noVowels = x.replace("a", "*"),replace("e", "*");

    etc etc

    it tells me error

    can anyone help?
    thanks in advance

    Using replaceFirst(String) and replaceAll(String)

    That gets into regex's which will be complicated for you, but will be needful to do it.

    Probably Pattern pattern = Pattern.compile("aeiou");
    Matcher matcher = pattern.matcher(input string);

    Default loopty loop...

    Yeah... the following will produce a nastgram:
    Java Code:
    String noVowels = x.replace("a", "*"),replace("e", "*");
    You can't concatenate methods (although it's an interesting idea :-)...
    I would attack it with two nested for loops ... the first for will loop through the string and the second will loop through the string or array of vowels.

    I agree with Nicholas, regex would be a more solid approach but from the display of interesting arrangement of methods, I'm assuming that getting the nested for loops together will be a challenge.
