``++Optional++`` value can hold either a value or not. The value held in the ``++Optional++`` can be accessed using the ``++get()++`` method, but it will throw a 
``++NoSuchElementException++`` if there is no value present. To avoid the exception, calling the ``++isPresent()++`` or ``++! isEmpty()++`` method should always be done before any call to ``++get()++``.

Alternatively, note that other methods such as ``++orElse(...)++``, ``++orElseGet(...)++`` or ``++orElseThrow(...)++`` can be used to specify what to do with an empty ``++Optional++``.

== Noncompliant Code Example

----
Optional<String> value = this.getOptionalValue();

// ...

String stringValue = value.get(); // Noncompliant
----

== Compliant Solution

----
Optional<String> value = this.getOptionalValue();

// ...

if (value.isPresent()) {
  String stringValue = value.get();
}
----

or

----
Optional<String> value = this.getOptionalValue();

// ...

String stringValue = value.orElse("default");
