Reports declarations of <code>Collection</code> variables made by using the collection class as a type,
|
|
rather than an appropriate interface. The warning is not issued if weakening the variable type
|
|
will cause a compilation error.
|
|
<p>Example:</p>
|
|
<pre><code>
|
|
// Warning: concrete collection class ArrayList used.
|
|
int getTotalLength(ArrayList<String> list) {
|
|
return list.stream().mapToInt(String::length).sum();
|
|
}
|
|
|
|
// No warning, as trimToSize() method is not
|
|
// available in the List interface
|
|
void addData(ArrayList<String> data) {
|
|
data.add("Hello");
|
|
data.add("World");
|
|
data.trimToSize();
|
|
}
|
|
</code></pre>
|
|
A quick-fix is suggested to use the appropriate collection interface (e.g. <code>Collection</code>, <code>Set</code>, or <code>List</code>).
