Write a modular program that allows the user to enter a word or phrase and determines whether the word or phrase is a palindrome. A palindrome is a word or phrase that reads the same backwards as forwards. Examples include: civic, kayak, mom, noon, racecar, Never odd or even., and Was it a Rat I saw

import java.util.Scanner;

public class num10 {

   public static void main(String[] args) {

       Scanner in = new Scanner(System.in);

       System.out.println("Enter a word");

       String word = in.nextLine();

       String reversed = "";

       //Get the length of the string entered

       int length = word.length();

       //Loop through the string and reverse th string

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

           reversed = reversed + word.charAt(i);

       //Compare the two strings "word" and "reversed"

       if (word.equals(reversed))

           System.out.println(word+" is a palindrome");

       else

           System.out.println(word+" is not a palindrome");

   }

}

Explanation:

Since we know that a palindrome word is a word that reads the same forward and backward, The Idea here is:
