Inspectopedia Help

Instance field may not be initialized

Reports instance variables that may be uninitialized upon object initialization.


class Foo { public int bar; static { } }

Note that this inspection uses a very conservative dataflow algorithm and may incorrectly report instance variables as uninitialized. Variables reported as initialized will always be initialized.

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 | Initialization

Use the Ignore primitive fields option to ignore uninitialized primitive fields.

Here you can find the description of settings available for the Instance field may not be initialized inspection, and the reference of their default values.
