Solution

Sure, here is a simple Java program that reverses a given string:

import java.io.*;
import java.util.*;

public class Solution {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        String input = sc.nextLine();
        String reversed = new StringBuilder(input).reverse().toString();
        System.out.println(reversed);
    }
}

Here's how it works:

  1. We import the necessary classes. java.util.Scanner is used to read the input from the user.

  2. In the main method, we create a Scanner object to read the input string.

  3. We read the input string using sc.nextLine().

  4. We create a StringBuilder object with the input string, reverse it using the reverse() method, and then convert it back to a String using toString().

  5. Finally, we print the reversed string using System.out.println().
