Hello

I have to modify this program in two ways, and I am a REAL newbie.......PLEASE HELP.
1) Rewrite the program using fileReader and FileWriter streams
2) Write another program with buffered streams to
boost performance.
import java.io.*;
public class CopyFileUsingByteStream
{
// Main method: args[0] for sourcefile and args[1] for target file
public static void main(
String[] args)
{
// Declare input and output file streams
FileInputStream fis = null;
FileOutputStream fos = null;
// Check usage
if (args.length !=2)
{
System.out.println(
"Usage:
java CopyFileUsingByteStream fromfile tofile");
System.exit(0);
}
try
{
// Create file input stream
fis = new FileInputStream(new File(args[0]));
// Create file output stream if the file does not exist
File outFile = new File(args[1]);
if (outFile.exists())
{
System.out.println("file " + args[1] + " already exists");
return;
}
else
fos = new FileOutputStream(args[1]);
// Display the file size
System.out.println("The file " + args[0] + " has "+
fis.available() + " bytes");
// Continuously read a byte from fis and write it to fos
int r;
while ((r = fis.read()) != -1)
fos.write((byte)r);
}
catch (FileNotFoundException ex)
{
System.out.println("File not found: " + args[0]);
}
catch (IOException ex)
{
System.out.println(ex.getMessage());
}
finally
{
try
{
// Close files
if (fis != null) fis.close();
if (fos != null) fos.close();
}
catch (IOException ex)
{
System.out.println(ex);
}
}
}
}
THANKS !!! Mary Ellen
