Solution

Sure, here is a simple Java program that takes a user input string, reverses it, and then checks if it is a palindrome.

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        System.out.println("Enter a word: ");
        String word = scanner.nextLine();
        String reversedWord = new StringBuilder(word).reverse().toString();
        if(word.equalsIgnoreCase(reversedWord)) {
            System.out.println(word + " is a palindrome.");
        } else {
            System.out.println(word + " is not a palindrome.");
        }
    }
}

Here's how it works:

  1. We import the Scanner class which is used to get user input.
  2. We create a new instance of the Scanner class.
  3. We prompt the user to enter a word.
  4. We read the user's input using the nextLine() method of the Scanner instance.
  5. We create a new StringBuilder instance with the user's input, reverse it, and convert it back to a String.
  6. We compare the reversed word with the original word, ignoring case differences.
  7. If they are equal, we print that the word is a palindrome. Otherwise, we print that it is not a palindrome.
