Create a FileCopier class with the following contents:

import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;

public class FileCopier {
public static void main(String[] args) {
FileInputStream in = null;
FileOutputStream out = null;
try {
in = new FileInputStream("groceries.txt");
out = new FileOutputStream("groceries (copy).txt");
int c;
while ((c = in.read()) != -1) {
out.write(c);
System.out.print((char) c);
}
} catch (IOException e) {
e.printStackTrace();
} finally {
if (in != null) try { in.close(); } catch (IOException e)
{ e.printStackTrace(); }
if (out != null) try { out.close(); } catch (IOException e)
{ e.printStackTrace(); }
}
}
}
