Parameter name differs from parameter in overridden or overloaded method

Reports parameters whose names differ from the corresponding parameters of the methods they override or overload. While legal in Java, such inconsistent names may be confusing and decrease the documentation benefits of good naming practices.

Example:

  class Person {
    Person(String fullName) {}
  }
  class Child extends Person {
    Child(String name) { super(name); }
  }

After the quick-fix is applied:

  class Person {
    Person(String fullName) {}
  }
  class Child extends Person {
    Child(String fullName) { super(fullName); }
  }

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.

ParameterNameDiffersFromOverriddenParameter

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 | Naming conventions

Use the options to indicate whether to ignore overridden parameter names that are only a single character long or come from a library method. Both can be useful if you do not wish to be bound by dubious naming conventions used in libraries.
