public class ReverseStringWordByWordProgram

{

public static String reverseTheSentence(String inputString)

{

String[] words = inputString.split("\s");

String outputString = "";

for (int i = words.length-1; i >= 0; i--)

{

outputString = outputString + words[i] + " ";

}

return outputString;

}

public static void main(String[] args)

{

Scanner sc = new Scanner(System.in);

System.out.println("Enter Input String :");

String inputString = sc.nextLine();

String outputString = reverseTheSentence(inputString);

System.out.println("Input String : "+inputString);

System.out.println("Output String : "+outputString);

sc.close();

}

}

Answer 2

import java.util.Scanner;

public class StringManipulation {

public static void main(String[ ] args) {

// Accepting sentence and converting it into a String array.

System.out.print("Enter a Sentence - ");

String[ ] sentence = new Scanner(System.in).nextLine( ).split(" ");

// Printing sentence with the words in reversed order.

for (int i = sentence.length - 1; i >= 0; i- -)

System.out.print(sentence[i] + " ");

}
