Help using a method

[LOL123]

Hello
I need to make a program that will take as input a word. The program will call a method to reverse the word, the method will return the word to the main program.
I had no problem creating a program that will reverse the word, but I dont understand how to code a method. The method must be in a diffrent java file from the main program the main program will call the method using an object with the input word as a parameter.
Here is my code:

code:

import java.io.*; class reverse_method {   public static void main(String[] args)     throws java.io.IOException   {     BufferedReader br = new BufferedReader (new InputStreamReader (System.in));         String input = " ";         System.out.println ("Please enter a word:");     input = br.readLine();     int len = input.length();            char[] tempCharArray = new char[len];     char[] charArray = new char[len];         for (int i = 0; i < len; i++) {       tempCharArray[i] = input.charAt(i);     }     for (int j = 0; j < len; j++) {       charArray[j] = tempCharArray[len - 1 - j];     }     String reverseWord =  new String(charArray);     System.out.println(reverseWord);   } }

As I stated before I only need help to get my method working, that you for your time.

The Introduction to Java covers methods extensively. It also has some things to say about naming conventions.
