Unnecessarily qualified static access

Reports usages of static members unnecessarily qualified with the class name.

Qualification with the class is unnecessary when the static member is available in a surrounding class or in a super class of a surrounding class. Such qualification may be safely removed.

Example:

class Foo { static void foo() {} static int x; void bar() { Foo.foo(); System.out.println(Foo.x); } static void baz() { Foo.foo(); } }

After the quick-fix is applied:

class Foo { static void foo() {} static int x; void bar() { foo(); System.out.println(x); } static void baz() { foo(); } }

Use the inspection options to toggle the reporting for:

  • Static fields access:

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

  • Calls to static methods:

    void bar() { Foo.foo(); }

Also, you can configure the inspection to only report static member usage in a static context. In this case, only static void baz() { Foo.foo(); } will be reported.
