Can anyone help me out?

Hello everyone, I was wondering if you guys can help me out. I'm stuck on this assignment =(.......

This is what I need to do...

Write a program that analyzes a web server's log file to determine which computers have attempted to access that web server the most. Any class in the Java standard library is available for use on this assignment.

So far this is what I got...

Code Java:

---

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;
import java.util.*;
 
public class logfile
{
	public static void main(String[] args) throws IOException
 
	{
		String filename; //file name
 
		String log;
 
		String s;
 
		Map <String, Integer> name = new HashMap <String, Integer>();
 
 
		//create scanner object for keyboard input
 
		Scanner keyboard =  new Scanner(System.in);
 
		System.out.println("Enter a log file to be analyzed");
 
		filename = keyboard.nextLine();
 
		FileReader f = new FileReader(filename);
 
		BufferedReader inputFile = new BufferedReader(f);
 
		log = inputFile.readLine();
 
		while(log != null)
 
		{
 
           Scanner read = new Scanner(f);
 
           // if we put this it will print out all the info inside the the logs
 
           /*
            * while(log! = null)
            * {
            * 	System.out.println(log);
            * 
            * 	log = input.File.readLine();
            * }
            */
           while(read.hasNext())
 
           {
               while (read.hasNext())
 
                   if(read.next().contains("[client"))
 
                       break;
 
               if(read.hasNext())
               {
                   s = read.next();
 
                   s = s.substring(0, s.length()- 1);
 
                   System.out.println(s);
               }
               read.nextLine();
           }
			log = inputFile.readLine();
		}
 
		System.out.println("Found " + "_______" + " unique IP addresses.");
 
		System.out.println("The most suspicious are: ");
 
		System.out.println()
 
	}
}

Is there an error or problem? Can you explain what it is?

Do you have any specific questions?

Well in my assignment I have to test 3 logs, right now I tried running one of the logs but it didn't seem to work. I don't have errors in my code.

Please explain in some more detail.
Also add some debug println statements to the code to show variable values as they change.

I put the log file inside the LogFileAnalysis folder, then I run the program and the only thing that outputs is "Enter a log file to be analyzed".

What does the program do after it outputs that message?

Add some debug println statements to the code to show where execution flow goes and the variable values as they change.

For example show the value of log before entering the while statement?
