Exercise
File Copier
Objetive
Create a program to copy a source file to a destination file. You must use FileStream and a block size of 512 KB. An example usage might be:
mycopy file.txt e:\file2.txt
The program should handle cases where the source file does not exist, and it should warn the user (but not overwrite) if the destination file already exists.
Example Code
public class Main
{
public static void main(String[] args)
{
final int BUFFER_SIZE = 512 * 1024;
byte[] data = new byte[BUFFER_SIZE];
java.io.FileInputStream inFile = File.OpenRead("1.exe");
java.io.FileOutputStream outFile = File.Create("1-copy.exe");
int amountRead;
do
{
amountRead = inFile.read(data, 0, BUFFER_SIZE);
outFile.write(data, 0, amountRead);
} while (amountRead == BUFFER_SIZE);
inFile.close();
outFile.close();
}
}
