AvoidProtectedFieldInFinalClass
Do not use protected fields in final classes since they cannot be subclassed.
Clarify your intent by using private or package access modifiers instead.
         

		
		
		    
    			
This rule is defined by the following XPath expression:
    			
    			
    

//ClassOrInterfaceDeclaration[@Final='true']
/ClassOrInterfaceBody/ClassOrInterfaceBodyDeclaration
/FieldDeclaration[@Protected='true']
 
                 
  
		    
		    
	    
	    
        
        
        
Example:
            
    
                

public final class Bar {
 private int x;
 protected int y;  // <-- Bar cannot be subclassed, so is y really private or package visible???
 Bar() {}
}
