Question

This is a JAVA language

The files provided in the code editor to the right contain syntax and/or logic errors. In each case, determine and fix the problem, remove all syntax and coding errors, and run the program to ensure it works properly.

Note: DebugData2.txt does not need to be edited. It is used by the program.

DebugData2.txt

435-9845
239-9845
981-9883
384-5656
875-3784
874-8120

DebugThirteen2.java

// Program reads in a file of phone numbers without area codes
// inserts "(312) " in front of each phone number
// and produces an output file with the new complete phone numbers
import java.nio.file.*;
import java.io.*;
import java.nio.channels.FileChannel;
import java.nio.ByteBuffer;
import static java.nio.file.StandardOpenOption.*;
public class DebugThirteen2
{
public static void main(String[] args)
{
Path fileIn =
Paths.get("/root/sandbox/DebugData2.txt");
Path fileOut =
Paths.get("/root/sandbox/DebugData2New.txt");
String areaCode = "(312) ";
String phone;
InputStream input = nul;
OutputStream output = nul;
try
{
input = Files.newInputStream(fileIn);
BufferedReader reader = BufferedReader
(new InputStreamReader(input));
output = Files.newOutputStream(fileOut);
phone = reader.readLine();
while(phone = null)
{
phone = areaCode + phone + System.getProperty("line.separator");
byte phoneBytes = phone.getBytes();
output.write(phoneBytes);
phone = reader.readline();
}
input.closes();
output.closes();
}
catch (IOException e)
{
System.out.println(e);
}
}
}
