HOw to check the extension in java

-----------------------------------

This is what i have to do

Write a program that prompts the user for a file name (including the extension), checks the extension and responds with a comment about the type of file, for example ?

	.doc	?	That was a Word document!
	.xls 	?	That was an Excel spreadsheet!
	.java	?	That was a Java source file!


My code so far

import java.util.Scanner;

import java.io.*;
class string
{
	public static void main(String[] args) throws Exception
	{
	Scanner in = new Scanner(System.in);


		
		String extension; 
		System.out.println ("Please enter a file name with extension.");
		
		extension = in.nextLine();

                Scanner s = new Scanner(extension);


                s.findInLine(.doc);

                 
		

                
		
		
                if (s.equals(.doc))
		{
		
		System.out.println ("doc file.");
		}
		else
		{
		
		System.out.println ("none.");
		}
		
		}
		}

I can't seem to figure out, any ideas
