I need help with java to apex

I need help with converting this java code:

public class Example{
  public static void reverseWordInMyString(String str){
   String[] words = str.split(" ");
   String reversedString = "";
   for (int i = 0; i < words.length; i++){
       String word = words[i];
       String reverseWord = "";
       for (int j = word.length()-1; j >= 0; j--){
  
         reverseWord = reverseWord + word.charAt(j);
      }
     reversedString = reversedString + reverseWord + " ";
   }
   System.out.println(str);
   System.out.println(reversedString);
  }
}

 

so far this is what i got :

public class Example {
    public static void reverseWordInMyString(String str){
        String[] words = str.split(' ');
        String reversedString = '';
        Integer i;
        Integer j;
        for(i=0; i<words.length(reversedString); i++){
            String reverseWord="";
            for(j = words.length(reverseWord)-1; j>=0; j--){
                reverseWord=reverseWord + word.charAt(j);
            }
            reversedString = reversedString + reverseWord + "";
        }
        System.debug(str);
        System.debug(reversedString);
    }
}
