Reverse a string in Java on repl it

Question

Below is my main code which gets the String from the user:

import java.util.Scanner;

public class Main {

    public static void main(String[] args) {

        Scanner inp = new Scanner(System.in);

        System.out.println("enter a number");

        int i = inp.nextInt();

        int o =i+i;

        System.out.println(o);

    }

    Scanner inp = new Scanner(System.in);

    System.out.print("In:");

    String word = inp.nextLine();

    int counter = word.length();

    for(counter>0){

        System.out.println(word.charAt(counter));

        int counter-1;

    }

}

This are the errors I get:

exit status 1

    System.out.print("In:");   

                    ^

Can anyone tell me how to reverse a String on repl.it? 

Answer 1

Check the below code: 

public static void main(String [] args) {

    try (Scanner scanner = new Scanner(System.in)) {

        System.out.println("In: ");

        String word = scanner.nextLine();

        System.out.println(new StringBuilder(word).reverse());

    } catch (Exception e) {

        e.printStackTrace();

    }

}
