Prompt:

You have been given a string s, which is supposed to be a sentence. However, someone forgot to put spaces between the different words, and for some reason, they capitalized the first letter of every word. Return the sentence after making the following amendments:

Put a single space between the words. Convert the uppercase letters to lowercase.

Any suggestions on my code?

String amendTheSentence(String s) {     StringBuilder modifiedString = new StringBuilder();     char[] sToArray = s.toCharArray();     if (Character.isUpperCase(sToArray[0])) {         modifiedString.append(Character.toLowerCase(sToArray[0]));     } else {         modifiedString.append(sToArray[0]);     }      for (int i = 1; i < sToArray.length; i++) {         char currentChar = sToArray[i];          if (Character.isUpperCase(sToArray[i])) {            currentChar = Character.toLowerCase(currentChar);             modifiedString.append(" ");         }          modifiedString.append(currentChar);     }     return modifiedString.toString(); }
