Only insertion operator can be overloaded among all the given options. And the polymorphism can be illustrated here only if any of these is applicable of being overloaded.
What is operator overloading?
Operator overloading is a function where different operators are applied and depends on the arguments. What is an abstract class? An abstract class is a class which cannot be instantiated. Creation of an object is not possible with an abstract class, but it can be inherited.
An abstract class can contain only Abstract method. Java allows only abstract method in abstract class while for other languages allow non-abstract method as well. What is a ternary operator? The ternary operator is said to be an operator which takes three arguments. Arguments and results are of different data types, and it depends on the function.
The ternary operator is also called a conditional operator. What is the use of finalize method? Finalize method helps to perform cleanup operations on the resources which are not currently used.
Finalize method is protected, and it is accessible only through this class or by a derived class. What are different types of arguments? A parameter is a variable used during the declaration of the function or subroutine and arguments are passed to the an, and it should match with the parameter defined.
There are two types of Arguments.
Call by Value — Value passed will get modified only inside the function, and it returns the same value whatever it is passed it into the function. Call by Reference — Value passed will get modified in both inside and outside the functions and it returns the same or different value.
What is the super keyword? Super keyword is used to invoke the overridden method which overrides one of its superclass methods. This keyword allows to access overridden methods and also to access hidden members of the superclass. It also forwards a call from a constructor to a constructor in the superclass.
What is method overriding? Method overriding is a feature that allows a subclass to provide the implementation of a method that overrides in the main class. This will overrides the implementation in the superclass by providing the same method name, same parameter and same return type.
What is an interface? An interface is a collection of an abstract method.Object-oriented programming (OOP) is a programming paradigm that represents the concept of "objects" that have data fields (attributes that describe the object) and associated procedures known as methods.
Welcome to our course on Object Oriented Programming in Java using data visualization. People come to this course with many different goals -- and we are really excited to work with all of you! Some of you want to be professional software developers, others want to improve your programming skills to.
A software object's behavior is exposed through ___. Hiding internal data from the outside world, and accessing it only through publicly exposed methods is known as data ___. A blueprint for a software object is called a ___.
