Redundant field initialization

Reports fields explicitly initialized to their default values.

Example:

  class Foo {
    int foo = 0;
    List bar = null;
  }

After the quick-fix is applied:

  class Foo {
    int foo;
    List bar;
  }

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.

RedundantFieldInitialization

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 | Code style issues

Use the inspection settings to only report explicit null initialization, for example:

  class Foo {
    int foo = 0;     // no warning
    List bar = null; // redundant field initialization warning
  }

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