Console app that reads/writes data files

Another basic question, but i'd like to keep this program as simple as possible.

I have numerous txt files that I want to read, just using the text console, not using any graphical interface options of Java.

easiest way to go about this?

i.e. i've got a txt file with a bunch of names/phone #'s that I want to open..

so basically I want the finished product to look like.

Enter file name: xxx.txt


John Doe 123-4567
John Smith 123-4567

Enter output file name: xxx.txt
Done saving file xxx.txt

Easy enough. Just read from the file as you normally would and print out the data.

Code:

---


File f = new File("myfile.text");


BufferedReader br = new BufferedReader(new FileReader(f) );

String line = "";
while ( (line = br.readLine()) != null)
{
  System.out.println(line);
}

Something like that is how you read from a file. That was done off the top of my head in about 30 seconds so it may have errors.

I give up, I guess i'm far more of a java rookie then I thought I was...

I just can't seem to put two and two together.

Am I getting anywhere here?

Code:

---

import java.io.*;

public class PhoneBook
{
  public static void main(String[] args) throws IOException
  {

          BufferedReader dataIn = new BufferedReader(new InputStreamReader(System.in));

          //Declaring Variables
          String InputFileName;
          String OutputFileName;

          //Get Input from User
          System.out.print("Enter Input File Name: ");
              InputFileName = dataIn.readLine();
          System.out.print("\nEnter Output File Name: ");
              OutputFileName = dataIn.readLine();
  }


}

I beleive, you are not going anywhere with that!

Have you ever been asked by a computer program to enter the input or output file?
