一次移动两个字母（子字符串）Java

Question

So I have my whole program working, it even moves on letter if it isn't a vowel, however it's suppose to move the two constant if they are right next to each other. So I have messed around with the substrings and making the char at (0) a variable, but still haven't got any luck any ideas?

So it would be the if (true) part.

Here is my code:

You can use regex match look for the vowels and return the first occurrence. The code snippet below will look for the first vowel in the word and return the its index. Then you can use that in your substring instead of just taking the first letter.

String word = "test";
Pattern pattern = Pattern.compile("[aeiou]");
Matcher matcher = pattern.matcher(word); 
if(matcher.find()){
  System.out.println(matcher.start());
}
