Redundant type cast

Reports unnecessary cast expressions.

Example:

  static Object toObject(String s) {
    return (Object) s;
  }

Locating this inspection

By ID

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

RedundantCast

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 | Verbose or redundant code constructs

Use the checkbox below to ignore clarifying casts e.g., casts in collection calls where Object is expected:

  static void removeFromList(List<String> l, Object o) {
    l.remove((String)o);
  } 

Here you can find the description of settings available for the Redundant type cast inspection, and the reference of their default values.
