Null Pointer Exception Using Optional at Daniel Kinsey blog

Null Pointer Exception Using Optional. If you cannot be sure that the value will not be null, then use optional.ofnullable(.,); Yes, optional.of will throw an exception if you pass a null value. The main purpose of using optional is to avoid dealing with null values directly, thereby reducing the possibility of nullpointerexceptions and making the code more readable and safe. How does an optional fix the problem? We use the ternary operator very often for checking null condition and return an alternative value or default value. Take a look at the code. As a result, you protect your code against unintended null pointer exceptions. At a very high level, a nullpointerexception is a runtimeexception that happens when you try to access a variable, but this variable is pointing to no object. One just has to wonder why they did not make it the default behaviour with the short name. In addition, optional forces you to actively unwrap an optional to deal with the absence of a value; Nullpointerexception is thrown when program attempts to use an object reference that has the null value.
