Suspicious collection method call

Reports method calls on parameterized collections, where the actual argument type does not correspond to the collection's elements type.


List<Integer> list = getListOfElements(); list.remove(""); // remove is highlighted

Locating this inspection


Can be used to locate inspection in e.g. Qodana configuration files, where you can quickly enable or disable it, or adjust its settings.

Via Settings dialog

Path to the inspection settings via IntelliJ Platform IDE Settings dialog, when you need to adjust inspection settings directly from your IDE.

Settings or Preferences | Editor | Inspections | Java | Probable bugs

In the inspection settings, you can disable warnings for potentially correct code like the following:

public boolean accept(Map<Integer, String> map, Object key) { return map.containsKey(key); }

Inspection options
