In the article "What if null was an object in Java?" on Medium, Don Raab explores the intriguing concept of treating `null` as an object in Java programming. He discusses how this approach could potentially eliminate `NullPointerExceptions`, a common source of bugs in Java applications. By considering `null` as a special singleton instance of every class, developers could invoke methods on `null`, which would return default values instead of causing crashes. Raab illustrates this idea using examples from the Eclipse Collections framework, where defaultIfNull and ifNotNull behaviors are implemented to handle null values gracefully. This concept challenges traditional programming practices and encourages thinking about more robust code handling strategies.
