Use a stack to reverse the words of a sentence. Keep reading words until you have a word that ends in a period, adding them onto a stack. When you have a word with a period, pop the words off and print them. Stop when there are no more words in the input. For example, you should turn the input Mary had a little lamb. Its fleece was white as snow. into Lamb little a had mary. Snow as white was fleece its. Pay attention to capitalization and the placement of the period. This is what I have so far: import java.util.Scanner; import java.util.Stack; /**    Class for reversing the order of a sentence. */ public class SentenceReverser {    /**       Reverses the given sentence.       @param sentence Sentence to be reversed.       @return Reversed sentence.    */    public static String reverse(String sentence)    {       String reversed = "";       Scanner scanner = new Scanner(sentence);       Stack stack = new Stack();       // put your work below       // ...              return reversed;    }    public static void main(String[] args)    {       String sentence = "Mary had a little lamb. Its fleece was white as snow.";       String reversed = SentenceReverser.reverse(sentence);       System.out.println("Given: " + sentence);       System.out.println("Expected: Lamb little a had mary. Snow as white was fleece its.");       System.out.println("Actual: " + reversed);    } }

Question

Use a stack to reverse the words of a sentence. Keep reading words until you have a word that ends in a period, adding them onto a stack. When you have a word with a period, pop the words off and print them. Stop when there are no more words in the input. For example, you should turn the input

Mary had a little lamb. Its fleece was white as snow.

into

Lamb little a had mary. Snow as white was fleece its.

Pay attention to capitalization and the placement of the period.

This is what I have so far:

import java.util.Scanner;
import java.util.Stack;

/**
   Class for reversing the order of a sentence.
*/
public class SentenceReverser
{
   /**
      Reverses the given sentence.
      @param sentence Sentence to be reversed.
      @return Reversed sentence.
   */
   public static String reverse(String sentence)
   {
      String reversed = "";
      Scanner scanner = new Scanner(sentence);
      Stack<String> stack = new Stack<String>();

      // put your work below
      // ...
      
      return reversed;
   }

   public static void main(String[] args)
   {
      String sentence = "Mary had a little lamb. Its fleece was white as snow.";
      String reversed = SentenceReverser.reverse(sentence);
      System.out.println("Given: " + sentence);
      System.out.println("Expected: Lamb little a had mary. Snow as white was fleece its.");
      System.out.println("Actual: " + reversed);
   }
}
