Default Sort the files in folder

I am making a webpage which shows all the file in a folder and make links to the file. However i want to know how i can sort the view of files according to file name or date created of by size(any one). I am using the for loop statement for displaying all the files.what modification should i do so that all the files are shown alphabetically in acending order...Also the file size is shown in bytes as a default. How can i make these appear in mb or kb to decimal digits....Pl help me out... the code which i am using is given below

<tr>
<td style="width: 164px"><br />
<a href="patches/<%=file.name%>"><%=file.name%></a></td>

Here's an example of how to do it by name. Date is trickier cf. http://forum.java.sun.com/thread.jsp...sageID=1850175

Code:
import java.util.*;   
import java.io.File;

public class FileSort {
  public static void main (String argv[]) {
    System.out.println("Sorted list of files example");
    File cwd = new File(".");        // current working directory
    String[] files = cwd.list();     // array of Strings of filenames
    Arrays.sort(files, String.CASE_INSENSITIVE_ORDER); // sorts them
    for (int i=0;i<files.length;i++) {
      System.out.println(files[i]);  // prints them
    }
  }

}
Gives me:

Code:
charlie@mogadon:~/filesort$ ls -1r
random
FileSort.java
FileSort.class
aaa
charlie@mogadon:~/filesort$ javac FileSort.java
charlie@mogadon:~/filesort$ java FileSort
Sorted list of files example
aaa
FileSort.class
FileSort.java
random
charlie@mogadon:~/filesort$
HTH,
Charlie
