Program to take name as input and write it backwards

Can someone please help me with my programming project?

The directions are:
Solution must employ at least one method other than the main() method. Program should be annotated. An explanation of all features of the program.

I'm trying to make a working program that takes your name and writes it backwards. Is that possible?
Can someone please help me write this and give an explanation. Please! I need this ASAP!

Thanks!

hi,

here is my code. hope it helps.

Code :

---

 
import java.io.*;
 
public class WordInverter {
 
 
 
 private static BufferedReader br= new BufferedReader(new InputStreamReader(System.in));
 
    public  static void main(String[] args)throws IOException
 
     { 
 
       String strInv = null,word;
 
        System.out.print("Enter a word : ");
        word=br.readLine();
        strInv = invert(word);
 
 
    System.out.println("The inverted word  : " + strInv);
 
 
      }
 
//another method
    public static String invert (String s) {
         String temp = "";
         for (int i=s.length()-1; i>=0; i--)
              temp += s.charAt (i);
         return temp;
    }
 
}

Hello snake101 and welcome to the Java Programming Forums.

Yes what you are trying to do is possible.

I would use the Scanner class to read in the persons name from the console and then use the StringBuffer reverse() method to reverse the String.

Here is an example. You can comment it yourself.

Code :

---

import java.util.Scanner;
 
public class Snake101 {
 
    /**
     * JavaProgrammingForums.com
     */    
    private static String name, nameReversed;
 
    public static void reverse(String n){
 
        nameReversed = (new StringBuffer(n)).reverse().toString();
        System.out.println(nameReversed);
    }
 
    public static void main(String[] args) {
 
        Snake101 snake = new Snake101();
        Scanner sc = new Scanner(System.in);
        System.out.println("Enter your name:");
        name = sc.next();
        snake.reverse(name);
        sc.close();        
    }
 
}

Well have you main function prompt for the name and then pass it to a function called reverse that returns the revrse of thee String given to it and then print it out :)

Code :

---

public class snake{
     public static void main(Sting[] args){
          System.out.print("Please enter your name: ");
          String name = (new Scanner(System.in)).nextLine();
          System.out.println("The reverse of your name is: " + this.reverse(name) );
     }
 
     private static String reverse(String name){
          // You can write the reverse function, or at least have a shot
          return reversedName;
     }
}

You are spoilt for choice snake101 b-)

Thank you for your post Truffy. That is a good way to reverse a String, although the StringBuffer reverse() method is much easier IMO.

Good posts guys, shame I wasn't willing to give an answer straight away :P. Imight have to adapt my style so that my answer is as helpful as other when we post at the same time hehe :P

Well this was my first post of the morning. I was feeling kind! Nothing like a Java problem & a cup of coffee to wake you up.
