Thread: Connecting GUI with application

Hi,

I need help to connect my GUI with my application. Both works well individually. When the user clicks on the load function in the GUI the user is should be able to load any txt file in to the system (which is working). The problem is executing the function which is in another java file. How do i go about it? Can someone help? This is the source code:

Hello... Sorry, I am using a mobile app to access this forum, and I am not in the 'mood'to go to my desktop to analyze your source, so could you please clarify what you are intending to do, so I can help direct you in getting a solution.

Thanks,

Michael.

My aim to extract and print out sentences from the loaded txt file. The document.java is able to do this but I have pre programmed one txt in it for testing(Legal.txt), which works perfectly fine. The GUI( FileDialogDemo.java) can load any document inside as it has JFileChooser and it work fine.But i need both of this work together. For example, I load any txt file inside the GUI it should be able to preform the works of document.java when i click a button in the GUI. How do i go about it?
