Mar 19, 2010 · Correct me if I am still confused - 1. ClassName.methodName() is the best practice to invoke static methods in Java 2. Reference type matters when dealing with static methods and NOT the instantiated type 3. We can hide static methods in subclass but CAN'T override even though the code looks like its overriding the method. –
No, we cannot override static methods because method overriding is based on dynamic binding at runtime and the static methods are bonded using static binding at compile time. So, we cannot override static methods. The calling of method depends upon the type of object that calls the static method. It means:
Feb 8, 2010 · Despite Java doesn't allow you to override static methods by default, if you look thoroughly through documentation of Class and Method classes in Java, you can still find a way to emulate static methods overriding by following workaround: import java.lang.reflect.InvocationTargetException;
Jan 31, 2012 · 1. No. You can't override a static method. It wouldn't really make sense to anyway. Since you don't need an instance of the class, you don't need polymorphic behavior. You would just change the all from SomeParent.main() to SomeChild.main() answered Jan 31, 2012 at 17:18. Justin Niessner. 245k 40 413 542.
Jul 1, 2010 · 4. No. Static methods are tied to the class they're defined in. They're invoked through the class, not through an object, and there is no dynamic dispatch where overriding could happen. You're probably confused because Java allows you to invoke static methods through an object reference. That's generally considered a design error, and it does ...
May 23, 2017 · Instead of overriding the method directly, you can create a new static method in your other class and call that directly (NewClass.method ()) public static double calculateNewSalary(double salary){. return salary*1.03; //give a yearly increase. public static double calculateNewSalary(double salary){.
In the form that you are using there, you are explicitly specifying what class's static method_two to call. If method_three was a classmethod, and you called cls.method_two, you would get the results that you wanted: class Test: def method_one(self): print "Called method_one". @staticmethod.
Feb 17, 2017 · Well You can't override a static method. A static method can't be virtual, since it's not related to an instance of the class. The "overridden" method in the derived class is actually a new method, unrelated to the one defined in the base class (hence the new keyword). This is an important thing to understand: when types inherit from other ...
Mar 28, 2014 · You get the ability to override a method by having an object provide it's own method instead of using the one provided by the parent. In the case of static methods there is no object to use to tell you which implementation to use. That means that the compiler can only use the declared type to pick the implementation of the method to call.
Sep 13, 2020 · When you do the same for a static method, the invoked version depends on from which class you invoke it. As for interfaces, static methods in interfaces are not inherited. Therefore it's technically not an override. In your example, you could call log() from class DD, or you could call log() from interface CC (in which case you'd need to call ...
