Questions tagged [static-methods]

Methods that neither require an instance of the class nor can they implicitly access the data (or this, self, Me, etc.) of such an instance.

Static methods neither require an instance of the class nor can they implicitly access the data (or this, self, Me, etc.) of such an instance. A static method is distinguished in some programming languages with the static keyword placed somewhere in the method's signature. Static methods are called "static" because they are resolved statically (i.e. at compile time) based on the class they are called on; and not dynamically, as in the case with instance methods which are resolved polymorphically based on the runtime type of the object. Therefore, static methods cannot be overridden.
