What does it mean to override a method in Java?

Overriding
In any object-oriented programming language, Overriding is a feature that allows a subclass or child class to provide a specific implementation of a method that is already provided by one of its super-classes or parent classes.

Why overridden method should not be more restrictive?

You can not make access modifier more restrictive, because that would violate the basic rule of inheritance that a subclass instance should be replacable in place of a superclass instance. For e.g Suppose that Person class has getName public method which is being used by many classes(including non-sub classes).

What is the advantage of method overriding in Java?

The main advantage of method overriding is that the class can give its own specific implementation to a inherited method without even modifying the parent class code.

What are rules of Method Overloading and overriding in Java?

Method Overloading is used to implement Compile time or static polymorphism. Method Overriding is used to implement Runtime or dynamic polymorphism. It is used to expand the readability of the program. The number of parameters and type of each parameter must be the same in case of method overriding.

Why method overriding is important?

The purpose of Method Overriding is that if the derived class wants to give its own implementation it can give by overriding the method of the parent class. When we call this overridden method, it will execute the method of the child class, not the parent class.

What is the function of override in Java?

Overriding in java is basically “Run time polymorphism”.

  • As the name suggests,polymorphism is basically an ability to take many forms (poly: many,morph: form).
  • Basically,the binding of function to object is done late,which is after compilation (i.

    • What is method override in Java?

    Java Method Overriding. Declaring a method in the subclass which already exists there in the parent class is known as method overriding. When a class is inheriting a method from a superclass of its own, then there is an option of overriding the method provided it is not declared as final. The advantage of using overriding is the ability to
