Here is solution for you, just convert that strings into date format and sort it
out

Here is simpler solution
Just compare two strings there is a function forgot name but go to String class
descirption on java.sun.com and you will find all sorts of functions that will
help operate on string, one of them ofcourse is string compare

Simple string comaprisions wont work here. APR2004 will be sorted sequentially
MAR2004. Many such situations may occur. Best Solution will be coverting to date
format based. This could be done in more than one way. Dumb rule would be to get
a substring of first three positions as month and last four positions as year
and implement some sort logic.

I tried & it's working fine... u can use it... (change the dir name to ur dir)


import java.io.*;
import java.text.*;

public class DateSort
{
public static void main(String args[])
{
try
{
SimpleDateFormat sdfDate = new SimpleDateFormat("MMMyyyy");
File fDir = new File("C:\\Vasanth\\Java\\MyDirectory");
File files[] = fDir.listFiles();
long lDates[] = new long[files.length];

for(int i=0;i<files.length;i++)
{
lDates[i] = sdfDate.parse(files[i].getName()).getTime();
}

for(int i=0;i<lDates.length;i++)
{
for(int j=0;j<i;j++)
{
if(lDates[i] < lDates[j])
{
File fTemp = files[i];
long lTemp = lDates[i];

files[i] = files[j];
lDates[i] = lDates[j];

files[j] = fTemp;
lDates[j] = lTemp;
}
}
}

for(int i=0;i<files.length;i++)
{
System.out.println(files[i].getName());
}
}
catch(Exception ex)
{
System.out.println(ex.toString());
}
}
}
