    Default BufferedReader starting to read on a line 3/4 of the way through the file, HELP!

    The code below is the first step I have taken to create a program for an assignment that
    is supposed to read from a file that contains information about gold medal winners from the Olympics.

    I have attached the .txt file I am using as my source for input.

    My problem is that for some reason, my BufferedReader starts reading a line 3/4 of the way through the file
    which is not what I need, I need it to start reading from the first line!

    Any help is greatly appreciated, my code is below!
    Thanks!

    import java.io.*;
     
    public class TestGoldMedals{
    	public static void main(String[] args){
    		BufferedReader input;
    		String line;
     
    		try{
    			input = new BufferedReader(new FileReader("a2a.txt"));
    			line = input.readLine();
     
    			while(line != null){
     
    				line = input.readLine();
    				System.out.println(line);
    			}
    			input.close();
    		}catch (IOException ioe){
    			System.out.println(ioe.getMessage());
    		}
    	}
    }

    Write out on paper what is happening...a line is read, then another line is read, then the line variable printed. You want to read a line, print a line, read a line print a line, etc...

    Yes so essentially, get rid of that first readLine() call after you instantiate the reader.

    I don't see though how it could be starting 3/4 of the way into the document? Are you sure?
