public class FileDemo
{

    public static void main(String[] args)
    {
        File file = new File("D:/work/myfile.txt");
        /*
         * Returns the length of the file denoted by this
         * abstract pathname. The return value is
         * unspecified if this pathname denotes a directory.
         * 
         * Returns: The length, in bytes, of the file
         * denoted by this abstract pathname, or 0L if the
         * file does not exist.
         */
        long length = file.length();
        System.out.println("length = " + length);
