Stack:

  • A stack is a linear data structure.
  • It follows the order FILO (first in last out) LIFO or (last-in-first-out) for performing operations on it.
  • The two main operations performed on a stack are,
    • Push() – Add item to the stack.
    • Pop() – Remove item from the stack.

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 inputMary had a little lamb. Its fleece was white as snow.intoLamb 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…
Implement a class called ReverseWords that uses a stack to output a set of elements input by the user in reverse order.
