Load file in GUI instead of notepad

[Kruptein]

In my program you can do: file->open file
you have to enter a name, and gedit (on linux) or notepad (on windows) loads the file,
is it possible to load the content of a file in a textbox?

current code

        logdialtext = "What is the name of the file? \n(it should be located in D_MENU/files)";
        textname = WelcomeMsg.showInputDialog(logdialtext);
        WelcomeText.setText("Opening " + textname);
        String editor = "gedit";
	File file = new File("/home/darragh/Documenten/D_MENU/files/" + textname);
        boolean exist = file.exists();
        if(exist) {
            try {
                Runtime.getRuntime().exec(editor + " " + file);
                WelcomeText.setText(textname + " Opened succesfull");
            } catch (IOException ee) {
                WelcomeText.setText(textname + " could not been opened");
            }
        } else {
            WelcomeText.setText(textname + " doesn't exist");
        }

PS: WelcomeText is a textbox

I found the solution on my own:

Scanner s = null;
        try {
            s = new Scanner(new BufferedReader(new FileReader("/home/darragh/Documenten/D_MENU/files/" + textname)));
            while (s.hasNext()) {
                WelcomeText.append("\n");
                WelcomeText.append(s.next());
            }
        } catch (IOException ex) {
            WelcomeText.setText("Couldn't open " + textname);
        } finally {
            if (s != null) {
                s.close();
            }
        }
