Length of a file ?

Just wondering, is there a way of finding out the length of a file without actually reading through until the end of the file ?

Using just pure jdk, so no wfc java stuff

Try using the File class and the length() method

Code:

---

import java.io.*;

class Test
{
        public static void main(String[] args)
        {
                try
                {
                        File f = new File("C:\\test.txt");
               
                        if (f.exists()) System.out.println(f.length()); //Length of the file in bytes
                }
                catch(Exception e){}
               
        }
}

Oh, and...WFC?? You've gotta be kidding :p

:)

Code:

---

File fileName = new File("c:\\autoexec.bat")
try
{
  System.out.println(fileName.length());
}
catch (Exception e)
{
  e.printStackTrace();
}

if i'm not mistaken :confused: :p

Thank you very much people, I can now put a nice percentage meter in my app :)

Lovely :)

Code:

---

    lenOfFile = (new File( "packet.txt" )).length();
