Is it possible to override static method

No,Static methods can't be overriden as it is part of a class rather than an object. But one can overload static method. Note: if we call a static method with object reference, then reference type class static method will be called, not object class static method.

The very purpose of using the static method is to access the method of a class without creating an instance for it.

It will make no sense if we override that method since they will be accessed by classname. No, you cannot override a static method. The static resolves against the class, not the instance. Each class has a static method getCName. When you call on the Class name it behaves as you would expect and each returns the expected value. No surprises in this unit test. But this is not overriding. This declaring something that has a name collision. If we try to reach the static from an instance of the class not a good practice , then it really shows:.

Even though cp is a Child, the static is resolved through the declared type, Parent, instead of the actual type of the object. For non-statics, this is resolved correctly because a non-static method can override a method of its parent.

You can overload a static method but you can't override a static method. Actually you can rewrite a static method in subclasses but this is not called a override because override should be related to polymorphism and dynamic binding.

The static method belongs to the class so has nothing to do with those concepts. The rewrite of static method is more like a shadowing. I design a code of static method overriding. I think It is override easily. Please clear me how its unable to override static members. Here is my code-. Refer static keyword. As any static method is part of class not instance so it is not possible to override static method. From Why doesn't Java allow overriding of static methods? Overriding depends on having an instance of a class.

The point of polymorphism is that you can subclass a class and the objects implementing those subclasses will have different behaviors for the same methods defined in the superclass and overridden in the subclasses. A static method is not associated with any instance of a class so the concept is not applicable.

There were two considerations driving Java's design that impacted this. One was a concern with performance: there had been a lot of criticism of Smalltalk about it being too slow garbage collection and polymorphic calls being part of that and Java's creators were determined to avoid that. Definitely, we cannot override static methods in Java.

Because JVM resolves correct overridden method based upon the object at run-time by using dynamic binding in Java. However, the static method in Java is associated with Class rather than the object and resolved and bonded during compile time.
