Unqualified static access

Reports usage of static members that is not qualified with the class name.

This is legal if the static member is in the same class, but may be confusing.

Example:

  class Foo {
    static void foo() {}
    static int x;

    void bar() {
      foo();
      System.out.println(x);
    }

    static void baz() { foo(); }
  }

After the quick-fix is applied:

  class Foo {
    static void foo() {}
    static int x;

    void bar() {
      Foo.foo();
      System.out.println(Foo.x);
    }

    static void baz() { Foo.foo(); }
  }

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.

UnqualifiedStaticUsage

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 toggle the reporting for the following items:

static fields access
void bar() { System.out.println(x); }
calls to static methods
void bar() { foo(); }
static void baz() { foo(); }

You can also configure the inspection to only report static member usage from a non-static context. In the above example, static void baz() { foo(); } will not be reported.
