User specifies file to be read in

Question

I'm working on a program to count the words, characters, etc in a text file. I've just about got it all working, but at the moment I've got it specified in the actual code which text file the program should perform the word count on, whereas I want to alter this so that ther user types in the name of the file to use.
At the moment, I have it like this:
class WordCounter
     public static InputStreamReader input = new InputStreamReader(System.in);
     public static BufferedReader keyboardInput = new BufferedReader(input);
     public static void main(String[] args) throws IOException
FileReader file = new FileReader("report.txt");
BufferedReader MyFile = new BufferedReader(file);
String Text = MyFile.readLine();
and then the program uses the "Text" string in performing its checks.
How do I alter it so it prompts the user to enter the filename?
Obviously
System.out.println("Please enter a filename:");
and then something to replace the fileReader code I currently have, but what exactly?
Any help much appreciated

Answer 1

Aha, it's working!
Replacing
FileReader file = new FileReader("report.txt");
with
System.out.println("Please enter a filename:");
FileReader file = new FileReader(keyboardInput.readLine());
produced the desired result.
Many thanks for that!!!
