I am trying to write a program that just reads and write an unbuffered steam, and reads and writes a buffered stream. Following the example on the java docs, I've got this for my buffered stream, which works fine.

import java.io.FileReader;
import java.io.FileWriter;
import java.io.IOException;

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

        FileReader inputStream = null;
        FileWriter outputStream = null;

        try {
            inputStream = new FileReader("unbufferedread.txt");
            outputStream = new FileWriter("unbufferedwrite.txt");

            int c;
            while ((c = inputStream.read()) != -1) {
                outputStream.write(c);
            }
        // Add finally block incase of errors.
        // Display error if input file is not found.
        } finally {
            if (inputStream != null) {
                inputStream.close();
            }
            if (outputStream != null) {
                outputStream.close();
            }
        }
    }
}

However the Java docs say "Here's how you might modify the constructor invocations in the CopyCharacters example to use buffered I/O:".

inputStream = new BufferedReader(new FileReader("bufferedread.txt"));
outputStream = new BufferedWriter(new FileWriter("bufferedwrite.txt"));

My question is how to implement it. Is it possible to add it all to one class? When I try to add it, I get an error saying:

"Cannot find symbol - class BufferedReader"

Any help would be great. Thanks.

You have to import the java.io.BufferedReader and java.io.BufferedWriter classes. Based on the code you posted, you aren't doing that. So just add the two lines:

import java.io.BufferedReader;
import java.io.BufferedWriter;
