FingletonDescriptionDerived from "field singleton,” a Fingleton is a class which contains static fields. Many will consider these edge cases and not want to report on them. CriteriaFingletons have at least one public static field. Examplepublic class Fingleton {
public static Foo instance;
}If the public static were for a field of type int or a String, and it were final then this would be a constant (and harmless) If it were public static and final and making a complex object, then it is not clear whether its harmless or not. The complexity of the class is important, but were making a blanket assumption here - Foo (as above) could be a very stateful and method-packed class. If it is then a system that is engineered in this way is no better than one that has fist-class singletons.
