Java

public class FileSizeTest {
   public static long getFileSize(String filename) {
       return new File(filename).length();
   }
   public static void test(String filename) {
       System.out.println("The following file called " + filename + 
           " has a file size of " + getFileSize(filename) + " bytes."
       );
   }
   public static void main(String args[]) {
        test("file", "input.txt");
        test("file", File.seperator + "input.txt");
