Given an array of Strings, words, return that array with all Strings of an even length replaced with an empty string

Question

Given an array of Strings, words, return that array with all Strings of an even length replaced with an empty string.

blankAllEvens( { "Hi", "there", "bob" }) => {"", "there", "bob"}
blankAllEvens({ "this", "is", "sparta!"}) => {"", "", "sparta!"}
blankAllEvens({ }) => {}

How do I return the string? I need to return the string in order to print blank space for the evens but right now I am just returning a count. This is my code I think everything is right, I just don't know how to return it?

public String[] blankAllEvens( String[] words ) {
 int cnt = 0;
  for (int i=0; i<words.length; i++) {
    if (words[i].substring(0, 1).equals("2")) {
  cnt++;
     }
  }
  return cnt; 
}

Here you go:

public String[] blankAllEvens( String[] words ) {
   for (int i=0; i <words.length; i++) {
      if (words[i].length() % 2 == 0) {
         words[i] = "";
      }
   }
   return words;
}

Basically, the if statement checks to see if the word in the array has an even length (we are dividing the word length by 2 and seeing if we get a remainder of 0); In that case, we blank it.
