    Default Connecting programs with Java

    Curious to know if anyone thinks this is possible or would know where to research the information needed to accomplish something like this,

    If I have three separate programs running on a computer. All three programs are meant for adding data too. Like Excel in fact Excel is one of them.

    If it possible to write a program in Java that would allow you to post all the data in it and then once submitted would automatically deliver the information to the sections of the other three programs running on the computer?

    If i understand correctly you want to take user inputs and pass information to three programs?. If this is the case then its very much possible.

    You can get information from user in anyway through console, GUI (swings) and take store them and pass it on when user submits the data.

    1) Essentially you need to have a program to capture data from user.
    2) Once user submits you need to segregate data and create instances of three programs and set the information to the objects.

    Right, that sounds amazing. But how would you go about segregating the data and create instances of three programs and set the information to the objects?

    --- Update ---

    what im trying to wrap my head around is how could java open up a program that it has no affiliation with and then enter data in to its columns.

    I would assume i can make a j frame with places for the user to enter the data in to and then i could store it in a data base. but once thats done how could i import it in to the other three programs?

    Does it mean that you want to persist data once user submits in these three programs?. If thats the case then you need to serialize the objects of these classes and de-serialize. Its like storing the state of the game and allowing user to restart it. Another way is to store this content in XML and read it once the app is started to pre-populate the data back into UI.

    Basically the three programs ask for the same data. so instead of opening each one and filling out the same thing over and over again I am trying to figure how to write something that will allow me to fill it out once and then it will transfer the data to the other three existing programs on its on.

    If the same information is to be stored in three programs then what to need is three instances of a class to store the information. Create a class to store information and do with it.

    You need to pass that information to 3 instances of your classes either in constructor or through setter methods.
