Static field used before initialization

Reports static variables that are read before initialization.

The inspection ignores equality checks with null.

Example:

  class Foo {
    public static int bar;

    public static void main(String[] args) {
      System.out.println(bar);
    }
  }

Note that this inspection uses a very conservative dataflow algorithm and may incorrectly report static 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.
