Seems like homework for me but dont want to discourage you.

Code:

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;

public class demo {

	public static void main(String args[]) {
		String data = null;
		int recCount = 0;

		try {
			FileReader fr = new FileReader("C:\\Development\\demo.txt");
			BufferedReader br = new BufferedReader(fr);
			data = new String();

			// For the first line thing
			data = br.readLine();

			if (data != null) {
				char[] allCharacters = data.toCharArray();
				for (int i = 0; i < allCharacters.length; i++) {
					System.out.println(allCharacters[i]);
				}
			}
			
			
			// For other lines 
			while ((data = br.readLine()) != null) {
				recCount++; // What is this for ??
				System.out.println(data);
			}

			// This should help you with substring as well
			System.out.println(data.substring(26, 53));

		}

		catch (IOException e) {
			System.out.println("IOException error!");
			e.printStackTrace();
		}

	}

}

Hope it helps
