Java: Closable

When working with multiple resources that need to be closed after we are done using, I particularly like the approach of using Closable Interface:


try {
    // open input streams and use them  
}
catch (IOException e) {
    e.printStackTrace();
}
finally {
    attemptClose(inputSteamA);
    attemptClose(inputSteamB);
}



private void attemptClose(Closeable object) {
    if (object != null) {
        try {
            object.close();
        }
        catch (IOException ignore) {
        }
    }
}
