Question

Create the following JAVA method:

the utility will reverse the characters in each word, where a word is a sequence of characters terminated by either a whitespace, if no delimiters are specified, or any single character in the string of delimiters, otherwise. Note that the end of the file always ends a word.

Answer 1

import java.util.*;
import java.util.Scanner;

  
class reverWords {

   static void wordRevese(String sentence)
   {
       //declare a character stack
Stack<Character> myStack=new Stack<Character>();

// Read till a space is found for the word
for (int i = 0; i < sentence.length(); ++i) {
if (sentence.charAt(i) != ' ')
   myStack.push(sentence.charAt(i));
//when space found
else {
while (myStack.empty() == false) {
System.out.print(myStack.pop());
}
System.out.print(" ");
}
}
// handling last word as it may not have a space at the end
while (myStack.empty() == false) {
System.out.print(myStack.pop());
  
}
}
  
public static void main(String[] args)
{
Scanner sc = new Scanner(System.in);
System.out.println("Enter the sentence:");
String sentence = sc.nextLine();

wordRevese(sentence);
sc.close();
}
}
