JFileChooser/Scanner/openFileReader

i want to make a dialog box to import a file and then use the buffered reader to use it. should i use (before the BufferedReader) the JFileChooser, the Scanner or the openFileReader? i tried to use all of them but i always got problems that i cant solve. :o

If you are using a gui a JFileChooser is an easy way to get a reference to a user–selected file. If using a console application you can use a JOptionPane to receive user input and pass the file path off to your BufferedReader.

Code:

---

BufferedReader br = null;

---

The reader is null. A NullPointerException is thrown when you attempt to access something that is null.

Code:

---

BufferedReader br = new BufferedReader(new InputStreamReader(System.in));

---

i had to initialize it thats why I typed null.
i want to use the JOptionPane.
anyway thanx for your reply. ;)
