TIOBE - Java Coding Standard

Rule: Design39

Synopsis:	An Interface should be used only to model a behaviour; consider converting this to a class
Language:	Java
Severity Level:	3
Category:	Design

Description:

An interface should be used only to model a behaviour of a class: using an interface as a container of constants is a poor usage pattern. The static import feature should always be considered as a replacement for this practice.

public interface ConstantsInterface {
     public static final int CONSTANT1=0;
     public static final String CONSTANT2="1";
    }
