Write a method that accepts a string object as an argument and displays its contents backward. for instance, if the string argument is "gravity" the method should display "ytivarg". demonstrate the method in a program that asks the user to input a string and then prints out the result of passing the string into the method.
below is a start on the code
package chapter8;
import java. util. scanner ;
/**
* your name
* chapter 8
* programming challenge 1
* provide a short description
*/
public class backwardstring{
public static void main(string[] args) {
string input; // to hold input
// create a scanner object for keyboard input.
// get input
// call the method below to display the string backwards.
}
/**
* the backward method accepts a string as an argument, and displays it
*backwards.
*/
public static void backward(string str) {
//for loop to reverse the string and print it
for ( ){
}
