Swing File Adder The program should not be able to blow up and make good use of exception handling. Handling and providing pop up messages for such conditions as: input file not found, output file cannot be created, and bad data in the input file, should all be implemented

Build a simple GUI.

When you click the process button it should read the in file and write to the out file that you have already selected. when you click the input button a J file chooser will pop up and allow you to browse to the file that you're going to read as input and then it places the full pathname in the input file name.

When you click on the output button it brings up a J file chooser select the path and type in the file name of the output file or select a previously file that you're going to overwrite with new output.

You will have a pre-created input file. Your input file is just a space separated input file that's all it is one space between each number and rows of numbers with one space between them.

The output file will take the number and add it to the next one and while there's still another one add plus symbols. When run out of data you had an equal sign. You must be adding them up along the journey to display the total at the end.
