    You usually show graphical data not "in the language" but in the Graphic User Interface produced by program written in the given language.

    In java popular (at least for beginners) approach is to use classes of Swing framework (included in standard API). You can find tons of examples, I think. Drawing on JPanel will give you graphs/charts all right.

    Of course you can also find some specific libraries, but I think that for pure beginner it is not the easiest way.

    Java should be able to display the data it receives when it receives it.

    @Norm: how to display the incoming data in java?
    when data is entered into java, can the data directly stored? if it can be directly deposited, where the data automatically stored?
    I still a beginner in java. thanks before.

    I still a beginner in java.
    This program will require more than a beginner.

    How is the data being received in the program? Does it come via a socket?
    When it receives the data, it can cause a method to display it and wait for the next input.
    The program will probably need threads.

    @Norm:
    If this is not for beginners, I would still learn.
    Yes, I think the data is received via a socket. But, can java socket storing data automatically?
    Can you teach me sir? Or there is a tutorial on this?

    There are many parts to this. Too many to cover here.

    A starting place is the Java tutorial: The Really Big Index
