Which feature of OOPS described the reusability of code? The general reason why Java is considered to be more secure than, say C, is because it handles memory management for you. Classes may inherit characteristics from other classes thanks to inheritance. How To Reuse Code In Object-Oriented Programming - Loginworks Reusability in OOP achieves through the features of C++ where it possible to extend or reuse the properties of parent class or superclass or base class in a subclass and in addition to that, adding extra more features or data members in the subclass or child class or derived class.This whole set of mechanism is known as Inheritance. Polymorphism is to indicate different tasks performed by a single entity. Multiple inheritance is not supported. Because a polymorphic object can operate on a variety of values and types, it can also be used in a variety of programs, sometimes with little or no change by the programmer.

The purpose of encapsulation and abstraction is to hide/group data into a single unit. In computer programming, Inheritance is an eminent concept in Object Orient Programming (OOPS) Paradigm. This mechanism actually inherits the fields and methods of the superclass. Reusability in OOP achieves through the features of C++ where it possible to extend or reuse the properties of parent class or super class or base class in a subclass and in addition to that, adding extra more features or data members in the subclass or child class or derived class. Parent classes, in other words, extend properties and behaviors to child classes. a programming language model in which programs are organized around data, or objects, rather than functions and logic. Because Java has four OOPS concepts: inheritance, encapsulation, polymorphism, and abstraction. The following are the concepts in OOPs-Object; Class; Inheritance . Which of the following syntax used to create an object of Class in Java?
