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.

Is 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?
