class FileWrite {
public static void main(String[] args) throws NumberFormatException, IOException {
FileOutputStream out = new FileOutputStream("output");
//Perform range checking
if(Integer.valueOf(args[0]) < 0 || Integer.valueOf(args[0]) > 255) {
throw new ArithmeticException("Value is out of range");
}
out.write(Integer.valueOf(args[0].toString()));
System.out.flush();
}
}

Note that a NumberFormatException results when attempting to use the Integer.valueOf() method, if args0 contains a value that is larger than the maximum value of an int.
