You can convert a checked exception to an unchecked by nestling it inside a RuntimException. If the exception is caught higher up in the stack and outputted using printStackTrace(), the stack for the original exception will be displayed as well.

try {

}
catch (IOException e) {
    throw new RuntimeException(e);
}

This is a good solution, that you shouldn't hesitate to use in these situations.
