Quick Answer: Why Java Does Not Allow Overriding A Static Method?

Can we override private and final methods?

private and final methods can be overloaded but they cannot be overridden.

It means a class can have more than one private/final methods of same name but a child class cannot override the private/final methods of their base class.

Argument list should be same in method Overriding..

What is method hiding?

Java 8Object Oriented ProgrammingProgramming. When super class and sub class contains same method including parameters and if they are static. The method in the super class will be hidden by the one that is in the sub class. This mechanism is known as method hiding.

Can a class contain both static and nonstatic methods?

Not only that, but while non-static classes may contain both static and instance methods, static classes are only allowed to have static methods. However, those static methods inside the instance class can not be called on the instance but only on the class itself. … // Calling the methods on the instance of the class.

Can static method override?

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

Why this Cannot be used in static methods?

The “this” keyword is used as a reference to an instance. Since the static methods doesn’t have (belong to) any instance you cannot use the “this” reference within a static method.

Can we override final method?

Any method that is declared as final in the superclass cannot be overridden by a subclass.

Can we override main method?

No, we cannot override main method of java because a static method cannot be overridden. The static method in java is associated with class whereas the non-static method is associated with an object.

Can we override protected method as private?

Yes, the protected method of a superclass can be overridden by a subclass. If the superclass method is protected, the subclass overridden method can have protected or public (but not default or private) which means the subclass overridden method can not have a weaker access specifier.

Can we inherit static method in Java?

Static methods are inherited in Java but they don’t take part in polymorphism. If we attempt to override the static methods they will just hide the superclass static methods instead of overriding them. This concept is not that easy as it looks. … We can access static members by extending the parent class also.

Why we Cannot override a static method in Java?

No, you cannot override static method in Java because method overriding is based upon dynamic binding at runtime and static methods are bonded using static binding at compile time.

Can you declare an overridden method to be static if the original method is not static?

Can you declare the override method as static while the original method is non-static ? Answer: No, you cannot, the signature of the virtual method must remain the same, only the keyword “virtual” is changed to keyword “override” .

Why we Cannot use this keyword in Static Block?

Can we use this keyword in static method? The answer is no because static method does not need any object to be called, and this keyword always point to a current object of a class. simply if there is no object then how the keyword point to any current object so,we cannot use this keyword here.

Can we use this () and super () in a method?

this() and super(), both are the constructors that’s why must be the first statement. But we can use both in a program. this(): It is used to call, same class Default or Parametrized Constructor. super(): It is used to call, immediate super/parent class Default or Parametrized Constructor.

Can we make constructor static?

No, we cannot define a static constructor in Java, If we are trying to define a constructor with the static keyword a compile-time error will occur. In general, static means class level. A constructor will be used to assign initial values for the instance variables.

Can we override private method?

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.
