By using the lastModified() method in java.io.File .

You can use lastModified() method in java.io.File class to get the time at which the file was last modified.
But you cannot get the time at which the file was last accessed / opened using java API.

Thx for the reply .

there r no java API which can tell me when was the file opened .

is there any way by which i can restrict the file to be get opened.

There's no Java API that reports when a file was last accessed because not all operating systems can tell you the needed information: UNIX can, but I don't think Windows can.

Likewise, there's not much of an API for file protection in Java because, again, not all OSs support that idea. There is a method setReadOnly() in java.io.File that lets you mark a file as read-only, but that's about it.
