Reports <code>java.util.Optional</code> or <code>com.google.common.base.Optional</code> types with an array or collection type parameter.
|
|
<p>In such cases, it is more clear to just use an empty array or collection to indicate the absence of result.</p>
|
|
<p><b>Example:</b></p>
|
|
<pre><code>
|
|
Optional<List<Integer>> foo() {
|
|
return Optional.empty();
|
|
}
|
|
</code></pre>
|
|
<p>This code could look like:</p>
|
|
<pre><code>
|
|
List<Integer> foo() {
|
|
return List.of();
|
|
}
|
|
</code></pre>
