If we did not have 'shorter-circuits' in Java, we'd receive a wide range of NullPointerExceptions in the above strains of code.

where by partialHits is usually a HashMap. What will transpire if the very first assertion is genuine? Will Java nevertheless check the next assertion? Since in order the main assertion to get accurate, the HashMap must not include the supplied key, Therefore if the second statement is checked, I will get NullPointerException.
