Thread: Opening a File for User

You could do something like this.

It's just an example but a JOptionPane will popup with YES and NO. If you click YES, the file will open.

		String fileName = "file.txt";
 
		// File written. Open?
		JOptionPane pane = new JOptionPane("file saved. Open file?");
		Object[] options = new String[] { "YES", "NO" };
		pane.setOptions(options);
		JDialog dialog = pane.createDialog(new JFrame(), "File Saved");
		dialog.show();
		Object obj = pane.getValue();
 
		int result = -1;
		for (int k = 0; k < options.length; k++)
			if (options[k].equals(obj)){
				result = k;
				String opt = Integer.toString(result);
				// if YES
				if(opt.equals("0")){
					// Open file
					Process p = Runtime.getRuntime().exec("cmd /c \""+fileName+"\"");			
				}else{
					// do nothing
				}
			}

This opens the file:

Process p = Runtime.getRuntime().exec("cmd /c \""+fileName+"\"");

You will need to import:

javax.swing.JOptionPane;
javax.swing.JDialog;
