Optional null value

 One way to handle a potential null value in Java is to use the Optional class. This class allows you to wrap the value that may be null in an Optional object, which provides a convenient way to handle the value without having to check for null. For example:

// Create an Optional object for the value that may be null
Optional<Integer> maybeValue = Optional.ofNullable(value);

// If the value is not null, print it
maybeValue.ifPresent(System.out::println);

// If the value is null, print a default value
System.out.println(maybeValue.orElse(0));

This allows you to handle the null value in a safe and concise way. You can also use the Optional class to perform additional operations on the value, such as mapping it to another value or filtering it based on certain criteria.

Alternatively, you can use the orElse() method of the Optional class to provide a default value if the Boolean object is null, as shown in the previous answer. This allows you to handle the null case in a safe and concise way. For example:

Boolean maybeValue = ...; // This could be null

// Convert the Boolean to a primitive boolean, or use a default value if it is null
boolean value = Optional.ofNullable(maybeValue).orElse(false);
