    renameTo of java.io.File. But beware, as javadoc states, that "Many aspects of the behavior of this method are inherently platform-dependent"

    i mean to say that when person put a sheet in the scanner machine, a scanner gui is appeared which ask in what format we need to save the scanned image
    so it just save the scanned image as scan_01.jpg

    i m creating an application where a gui will be present & person will fill the form in the gui, based on the information provided by person i want to rename the scanned image but scanner provide a default name

    So tell me how can i do that

    What do you want to control? The GUI of the scanner software? (Epson software has its scanner GUI, HP has its own, etc...). You can't (hardly) control that GUI directly, since it's different for each scanner producer.
    At native O.S. level there are apposite APIs, the TWAIN API and on Windows the WIA (Windows Image Acquisition) and others. This at native level (and I don't remember now if these APIs can control the filename).

    At Java level there is nothing "standard" and well known for this. There is something (please see this search on Google) but I don't known and never used.

    So sorry, you are asking an "hard" thing.

    You could tell this before .....

    Have you looked at page 15 of the developer guide of JTwain? It tells how to save the image to a file programmatically.
    Note: I never used JTwain ... It took me just 3 minutes to find this ....

    Another approach could be to use a FileSystem WatchService to wait for the creation of the file.
    If you don't understand my answer, don't ignore it, ask a question.

    See the Java SE 1.7 API doc for those classes: FileSystem and WatchService
    for a description of what they can do.
