I need a swing component for opening an existing CSV file in notepad or respective available viewer installed on machine and then after viewing give the capability to the user to save the 开发者_如何学Pythonfile.

Offer the user a JFileChooser to select the File then call Desktop.edit(File), is the easiest way to achieve that functionality.

Here it would probably load in Excel or OO.
