Hi again, please help! :)

Question

Hi guys...i posted this problem a while ago, (a week!) and u told me to use the method replaceALL('a','')... but i dont have Java 1.4. I figured out anyway, i just used substrings...rofl :)
But: Is there a shorter way? i am running Ready to program...v 1.0.0.9
Have fun
I need help, this is a question i just cant seem to decifer.
A simple way of shortening words is to remove all vowels (Like in tel. directories).
I must write a programm that will take as input a string (of up tp 255 chars) and pritn out the same string with the vowels removed. Vowels are a,e,i,o,u. I must remove lower and Upper case vowels. without changing case of reamining string. I am not allowed to change the sapcing or punctuation.

Here's a small example...
public class RemoveVowels
  public static final String stripVowels(String src) {
    return RemoveVowels
      .stripVowels(src, new StringBuffer(src.length())).toString();
  public static final StringBuffer stripVowels(String src, StringBuffer buf) {
    char[] ch = src.toCharArray(); // Faster then calling charAt(...) multiple times
    for (int i = 0; i < ch.length; i++) {
      switch (ch) {
case 'A': case 'a':
case 'E': case 'e':
case 'I': case 'i':
case 'O': case 'o':
case 'U': case 'u':
break;
default:
buf.append(ch[i]);
return buf;
public static void main(String[] args) {
for (int i = 0; i < args.length; i++) {
System.out.println(args[i]);
System.out.print(" => ");
System.out.println(RemoveVowels.stripVowels(args[i]));
The command 'java RemoveVowels "This is a test, can I remove vowels?"' gave the following output:
This is a test, can I remove vowels?
=> Ths s  tst, cn  rmv vwls?It's quite fast too...
