AvoidConstantsInterface
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.
      
		
		
		    
    			This rule is defined by the following XPath expression:
    			
    			
        
//ClassOrInterfaceDeclaration[@Interface="true"]
    [
     count(.//MethodDeclaration)=0
     and
     count(.//FieldDeclaration)&gt;0
    ]
    
        
  
		    
		    
	    
	    
        
        
        Example:
            
                    
    
    public interface ConstantsInterface {
     public static final int CONSTANT1=0;
     public static final String CONSTANT2="1";
    }
