Redundant 'Collection' operation
Reports unnecessarily complex collection operations which have simpler alternatives.
Example:
void f(String[] array, Collection<String> collection) {
String[] strings = Arrays.asList(array).subList(0, 10).toArray(new String[0]);
boolean contains = collection.containsAll(Collections.singletonList("x"));
}After the quick-fix is applied:
void f(String[] array, Collection<String> collection) {
String[] strings = Arrays.copyOf(array, 10);
boolean contains = collection.contains("x");
