Inspectopedia Help

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.

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