title: How to change characters within a character array in java
body: <p>So I am trying to change the vowels of this list of words. a would go to e, e would go to i, i would go to u, and u would go to a (Same for uppercase). For some reason my code doesn't seem to be changing the characters (that could be due to what I am printing out as well). Am I changing the characters in the character array and if so, is my output just incorrect? How should I fix this?</p>
  
  <p>The words we had to sort are here: </p>
