Is this java i/o code acceptable?

I was told to create a program that reads data from txt file, then sorts data based on < or > 0 and writes data to 2 different txt files. I've achieved my goal but I want to make sure there isn't a better way I could do it. The teacher mentioned BufferedReader(?).

---------------------------------------------------------

import java.util.Scanner;

import java.io.*;

public class Transactions

{

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

{

String line, name, file = "Transactions.txt";

File openFile = new File (file);

Scanner inFile = new Scanner (openFile);

PrintWriter posFile = new PrintWriter ("Deposits.txt");

PrintWriter negFile = new PrintWriter ("Withdrawals.txt");

while (inFile.hasNext())

{

double number = inFile.nextDouble();

System.out.println(number);

if (number < 0) negFile.print (number + " \r\n");

if (number > 0) posFile.print (number + " \r\n");

}

System.out.println("Deposits.txt and Withdrawal.txt files have been created.");

inFile.close();

negFile.close();

posFile.close();

}

}
