Checks that the order of modifiers conforms to the suggestions in the Java Language specification, sections 8.1.1, 8.3.1 and 8.4.3. The correct order is:
Checks for redundant modifiers in:
Rationale: The Java Language Specification strongly discourages the usage of public and abstract for method declarations in interface definitions as a matter of style.
Interfaces by definition are abstract so the abstract modifier on the interface is redundant.
Variables in interfaces and annotations are automatically public, static and final, so these modifiers are redundant as well.
As annotations are a form of interface, their fields are also automatically public, static and final just as their annotation fields are automatically public and abstract.
Final classes by definition cannot be extended so the final modifier on the method of a final class is redundant.
