Quick Answer: Can We Override Private Methods?

Can we override static method?

Can we Override static methods in java.

We can declare static methods with the same signature in the subclass, but it is not considered overriding as there won’t be any run-time polymorphism.

Hence the answer is ‘No’..

Can Final methods be overridden?

A final method in a superclass cannot be overridden in a subclass—this guarantees that the final method implementation will be used by all direct and indirect subclasses in the hierarchy. Methods that are declared private are implicitly final , because it’s not possible to override them in a subclass.

Can constructor be private?

Yes, we can declare a constructor as private. If we declare a constructor as private we are not able to create an object of a class. We can use this private constructor in the Singleton Design Pattern.

Are private methods final?

When we use final specifier with a method, the method cannot be overridden in any of the inheriting classes. Methods are made final due to design reasons. Since private methods are inaccessible, they are implicitly final in Java.

Can a constructor override?

Constructor looks like method but it is not. It does not have a return type and its name is same as the class name. But, a constructor cannot be overridden. If you try to write a super class’s constructor in the sub class compiler treats it as a method and expects a return type and generates a compile time error.

Why we can not override static method?

Static methods cannot be overridden because they are not dispatched on the object instance at runtime. The compiler decides which method gets called. Static methods can be overloaded (meaning that you can have the same method name for several methods as long as they have different parameter types).

Can subclasses access private methods?

Yes, a subclass can indirectly access the private members of a superclass. … All the public, private and protected members (i.e. all the fields and methods) of a superclass are inherited by a subclass but the subclass can directly access only the public and protected members of the superclass.

Can private methods be inherited?

A java private member cannot be inherited as it is available only to the declared java class. Since the private members cannot be inherited, there is no place for discussion on java runtime overloading or java overriding (polymorphism) features.

What happens if we override private method?

private methods are hidden inside their class. They cannot be invoked directly by outside callers, such as main method in your case, because they are encapsulated inside the class. They do not participate in method overrides. No, a private method cannot be overridden since it is not visible from any other class.

Can we change argument list of overridden method?

You can’t change the number of type parameters in the overridden method. As for your case, override clearly fails with the return type. But even if the return types were same, your method still wouldn’t be override equivalent, as you have fewer type parameters in the supposed-to-be overridden method.

Can we overload main method?

Yes, we can overload the main method in Java, but When we execute the class JVM starts execution with public static void main(String[] args) method.

Can private variables be inherited Java?

private variables / members are not inherited. That’s the only answer. Providing public accessor methods is the way encapsulation works. You make your data private and provide methods to get or set their values, so that the access can be controlled.

Can you override private methods?

No, we cannot override private or static methods in Java. Private methods in Java are not visible to any other class which limits their scope to the class in which they are declared.

Can we override private and final methods?

No, We can not override private method in Java, just like we can not override static method in Java. … private methods are not even visible to Child class, they are only visible and accessible in the class on which they are declared. private keyword provides highest level of Encapsulation in Java.

Are private methods inherited C++?

The private members of a class can be inherited but cannot be accessed directly by its derived classes. They can be accessed using public or protected methods of the base class. The inheritance mode specifies how the protected and public data members are accessible by the derived classes.
