Output says "The number of bytes in the file are 0" but the file has bytes

Question

Dear Java People,
Why would an output say a file has 0 bytes when upon doing a search for the file in Windows Explorer it say the file has 1 -4 kbytes ?
for example part of my output was :
"the number of bytes in TryFile3.java are 0"
caused by the following lines of code:
System.out.println("\n" + contents[i] + " is a " +
(contents.isDirectory() ? "directory" : "file\n") +
" last modified on " + new Date(contents[i].lastModified())
+ "\nthe number of bytes in TryFile.java are " + myFile.length());
thank you in advance
below are the two program classes

import java.io.File;
import java.io.FilenameFilter;
import java.util.Date;
public class TryFile3
   public static void main(String[] args)
       //create an object that is a directory
         File myDir =
        new File("C:\\Documents and Settings\\Gateway User\\jbproject\\stan_ch9p369");
          File myFile = new File(myDir, "TryFile3.java");
        System.out.println("\n" + myDir + (myDir.isDirectory() ? " is" : " is not")
        + " a directory.");
         System.out.println( myDir.getAbsolutePath() +
         (myDir.isDirectory() ? " is" : " is not") + " a directory.");
          System.out.println("The parent of " + myDir.getName() + " is " +
          myDir.getParent());
           //Define a filter for java source files Beginning with the letter 'F'
           FilenameFilter select = new FileListFilter("F", "java");
           //get the contents of the directory
           File[] contents = myDir.listFiles(select);
            //list the contents of the directory
         if(contents != null)
             System.out.println("\nThe " + contents.length  +
             " matching item(s) in the directory " + myDir.getName() + " are:\n " );
             for(int i = 0; i < contents.length; i++)
               System.out.println("\n" +  contents[i] + " is a " +
               (contents.isDirectory() ? "directory" : "file\n") +
" last modified on " + new Date(contents[i].lastModified())
+ "\nthe number of bytes in TryFile3.java are " + myFile.length());
else {
System.out.println(myDir.getName() + " is not a directory");
System.exit(0);

Answer 1

System.out.println("\n" + contents + " is a " +
(contents.isDirectory() ? "directory" : "file\n") +
" last modified on " + new Date(contents.lastModified())
+ "\nthe number of bytes in TryFile.java are " + myFile.length());I haven't read any of your italicized code, but perhaps there is a good reason why you have "myFile.length()" and not "contents.length()" in this line of code?
