Method can be made 'static'

Reports methods that can safely be made static. Making methods static when possible can reduce memory consumption and improve your code quality.

A method can be static if:

  • it is not synchronized, native or abstract,

  • does not reference any of non-static methods and non-static fields from the containing class,

  • is not an override and is not overridden in a subclass.

Use the following options to configure the inspection:

  • Whether to report only private and final methods, which increases the performance of this inspection.

  • Whether to ignore empty methods.

  • Whether to ignore default methods in interface when using Java 8 or higher.

  • Whether to let the quick-fix replace instance qualifiers with class references in calls to methods which are made static, that is, call myClass.m() would be replaced with MyClass.m().
