File size

In this task, the job is to verify the size of a file called "input.txt". Assuming current directory or fullpath. Either "/input.txt" or "\input.txt".

Java

import java.util.File;
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");
   }
}

Perl

   sub getFileSize($) {
       return -s $_[0];
   }
   sub test($) {
       print "The following file called " . $_[0] . 
           " has a file size of " . getFileSize($_[0]) + " bytes.";
   }
   test("file", "input.txt");
   test("file", "/input.txt");
   test("file", "\\input.txt");
   exit;
 
   # Short version
   print -s 'input.txt';
   print -s '/input.txt';
   print -s "\\input.txt";
