/*******************************Sentence.java****************/

public class Sentence {

   public char correctFirstLetter(char c) {

       if (Character.isUpperCase(c)) {

           return c;
       } else {

           return Character.toUpperCase(c);
       }
   }

   public String correctLowerAfterFirstChar(String remainingWord) {

       return remainingWord.toLowerCase();
   }

   public String correctEnd(String word) {

       if (word.endsWith(".")) {

           return word;
       } else {

           return word + ".";
       }

}

/***************SentenceTest.java****************/

public class TestSentence {

   public static void main(String[] args) {

       String corrected = execute("heLlo woRlD.");
   System.out.println(corrected);
   }

   public static String execute(String word) {

       Sentence sentence = new Sentence();
       char capitalFirst = sentence.correctFirstLetter(word.charAt(0));

       String correctLower = sentence.correctLowerAfterFirstChar(word.substring(1, word.length()));

       String correctEnd = sentence.correctEnd(correctLower);

       return capitalFirst + correctEnd;
