I know its a very specific question but this is the situation:
I am taking one file as an input using BROWSE dialog box of swing.
Now I am converting that file into other file.
So when conversion is completed.
At best I want that file to be opened in any editor
OR
may be we can just open a window which shows folder which contains that file as shown in fig.
Is this possible?

to open windows explorer window:
if you want to open the file using default application you can use Desktop class
