1. Backward String

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 passes it

to the method.

Solution

ReverseString.java

import java.util.Scanner;

public class ReverseString {

  
   public static void main(String[] args) {
           Scanner in = new Scanner(System.in);
           System.out.println(\"Enter the string :\");
           String str = in.nextLine();
           backwardString(str);
          
   }
   public static void backwardString(String str){
       System.out.println(\"Reverse String is :\");
       for(int i=str.length()-1 ; i>=0; i--){
           System.out.print(str.charAt(i));
       }
   }
  

}

Output:

Enter the string :
gravity
Reverse String is :
ytivarg
