Java Programming

If I have a Class clazz object, is it possible to determine if it implements Comparable without calling newInstance() against it?

This is the code I currently have, but I'd like to do the same thing without creating a variable that will immediately be thrown away.

	private boolean implementsComparable(Class clazz)
	{
		try
		{
			if (clazz.newInstance() instanceof Comparable)
			{
				return true;
			}
		}
		catch (Exception ex)
		{
                        // @TODO something about NPE's
			// ignore all exceptions here
		}
                return false;
	}

Thank you.
