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 40 414 544.

Answer : Yes, we can provide different implementation of main() declared in an interface and classes implementing that interface by overriding method and can overload static main method if defined in an interface.

And no, you can't do it (or to be precise: overload you can, just the JVM won't call the overloaded versions). The JVM is looking for a main method with a specific signature, namely taking a String[] parameter.

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){.
