Solution
Hi,
I have fixed the code. Highlighted the code changes below
DebugThirteen2.java
import java.nio.file.*;
import java.io.*;
public class DebugThirteen2
{
public static void main(String[] args)
{
Path fileIn =
Paths.get("C:JavaChapter.13DebugData3.txt");
Path fileOut =
Paths.get("C:JavaChapter.13DebugData3New.txt");
String areaCode = "(312) ";
String phone;
InputStream input = null;
OutputStream output = null;
try
{
input = Files.newInputStream(fileIn);
BufferedReader reader = new BufferedReader
(new InputStreamReader(input));
output = Files.newOutputStream(fileOut);
phone = reader.readLine();
while(phone != null)
{

3. phone = areaCode + phone + System.getProperty("line.separator");
byte[] phoneBytes = phone.getBytes();
output.write(phoneBytes);
phone = reader.readLine();
}
input.close();
}
catch (IOException e)
{
System.out.println(e);
}
}
}
