Avoid unnecessary modifiers in an "interface"

Description

This rule flags any unnecessary modifier used in "interface" members.

Interface methods are always "public" and "abstract". Interface fields are always "public", "static" and "final". It is thus unnecessary and confusing to add those modifiers when declaring "interface" fields or methods.

Example

 package UC;
 
 interface AAI
 {
     public void method ();  // Violation
     abstract int getSize ();  // Violation
     static int SIZE = 100;  // Violation
 }

Repair

 interface AAI_fixed
 {
     void method ();
     int getSize ();
     int SIZE = 100;
 }
