Can we have 2 main methods in Java?

A class can define multiple methods with the name main. The signature of these methods does not match the signature of the main method. These other methods with different signatures are not considered the “main” method. Yes it is possible to have two main() in the same program.

Which method Cannot be overridden?

A method declared final cannot be overridden. A method declared static cannot be overridden but can be re-declared. If a method cannot be inherited, then it cannot be overridden. A subclass within the same package as the instance’s superclass can override any superclass method that is not declared private or final.

What is overriding in OOP?

Method overriding, in object-oriented programming, is a language feature that allows a subclass or child class to provide a specific implementation of a method that is already provided by one of its superclasses or parent classes. … Some languages allow a programmer to prevent a method from being overridden.

Can we inherit private method in Java?

You can only call a private member method in its definition class. … say() because derived classes can’t inherit private methods from its base class. Only protected and public methods/variables can be inherited and/or overridden.

How can we override a method in inheritance?

Instance Methods The ability of a subclass to override a method allows a class to inherit from a superclass whose behavior is “close enough” and then to modify behavior as needed. The overriding method has the same name, number and type of parameters, and return type as the method that it overrides.

How do you call a superclass version of an overridden method?

Few suggestions : Don’t pass child class reference to super class and except super class method has to be invoked for overridden method. Call super class methods from super class instance. Don’t override super class method in child class.

Why we Cannot 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 we override static method?

If all you do is implement Cloneable, only subclasses and members of the same package will be able to invoke clone() on the object.

How do I access protected methods?

The methods or data members declared as protected can be accessed from:Within the same class.Subclasses of same packages.Different classes of same packages.Subclasses of different packages.
