file io - java try finally block to close stream

I want to close my stream in the finally block, but it throws an IOException so it seems like I have to nest another try block in my finally block in order to close the stream. Is that the right way to do it? It seems a bit clunky.

Here's the code:

 public void read() {
    try {
        r = new BufferedReader(new InputStreamReader(address.openStream()));
        String inLine;
        while ((inLine = r.readLine()) != null) {
            System.out.println(inLine);
        }
    } catch (IOException readException) {
        readException.printStackTrace();
    } finally {
        try {
            if (r!=null) r.close();
        } catch (Exception e){
            e.printStackTrace();
        }
    }


}

Also if you're using Java 7, you can use a try-with-resources statement:

try(BufferedReader r = new BufferedReader(new InputStreamReader(address.openStream()))) {
    String inLine;
    while ((inLine = r.readLine()) != null) {
        System.out.println(inLine);
    }
} catch(IOException readException) {
    readException.printStackTrace();
}
