Java uses the java.io.File class to give access to information about files such as date last modified, size, etc. - you should study the Javadocs for the File class.

Thanks for your reply, Let me explain so that there is better understanding of the propblem
I have list of files in a folder and now I want to know which of the file in the folder is latest modified, I also want to have the name of the file which last modified in the folder.
I showing a small code of it which I have written for it, I am able to get the last modified value but don't know how to get the last modified file name.
File f = new File("C:\\Documents and Settings\\Administrator\\Desktop\\modified");
File[] filePaths = f.listFiles();
for (int i = 0; i < filePaths.length ; i++) {
long fileCreatedTime = filePaths[i].lastModified();

Thanks,
Ajay

don't know how to get the last modified file name.

That is as simple as creating a couple of extra variables:

File newestFile = null ;
long newestTime = 0L;

Inside the loop - every time you get a last modified time greater than newestTime store the corresponding File in newestFile and the time stamp in newestTime.

At the end of the loop you are done - newestFile has the name
