Question 30 options: True//False //// In a state diagram, the guard depends on the active state of the object. The following are some of the advantages of encapsulation: Abstraction refers to the users interaction with just a subset of an objects characteristics and operations. The data and methods are then enclosed in the object when it is created from the class. Thus, OOP objects are reusable and may be utilized in several applications. Simple items are used to show complexity. Further, one is, object use is must, secondly, message passing and lastly, Dynamic binding. OOP concepts (OOP) intend to improve code readability and reusability by defining how to structure a Java program efficiently. Encapsulation.

Q1: Which are the best features of OOPs, and why explain?Ans: Encapsulation, inheritance, and polymorphism are three fundamental elements of object-oriented programming that distinguish it from non-OOP languages. These properties are put together within a single unit named class. Abstraction reveals just the most significant facts to the user while hiding the underlying intricacies. Method overriding and method overloading are two ways that polymorphism enables the same method to perform various actions.

Some features of Object Oriented programming are as follows: Emphasis on data rather than procedure; Programs are divided into Objects There are three major features in object-oriented programming that makes them different than non-OOP languages: encapsulation, inheritance and polymorphism. Encapsulation and Abstraction are two features of OOPs that are the same. Because Java compiles as bytecode which then runs inside a Virtual machine, it cannot access the computer it runs on like a natively compiled program can. Write unit tests for your classes AND make it easy to test classes. Share. Inheritance is the feature of OOPS, which allows the users of OOPS to reuse the code which is already written. The Object oriented programming makes it easier to the programmers to design and organize software programs.

Object-oriented programming (OOP) is defined as a programming paradigm (and not a specific language) built on the concept of objects, i.e., a set of data contained in fields, and code, indicating procedures - instead of the usual logic-based system. It makes the data partitioned into two memory areas, i.e., data and functions, and helps make the code flexible and modular. There is no possibility that someone maintaining the code may inadvertently point to or otherwise access the wrong data . Code Reusability : The existing code in object oriented programming can be reused by the feature referred to as inheritance. Which Feature of OOP illustrated the code reusability? Which feature of OOP indicates code reusability? Explanation: Inheritance allows you to reuse your already written code by inheriting the properties of written code into other parts of the code, hence allowing you to reuse the already written code. Dynamic Binding which is also known as Late binding or run-time binding, is a process of executing the part of the code at runtime. 1. c. Polymorphism. If a function can perform more than 1 type of tasks, where the function name remains same, which feature of OOP is used here? To provide the feature of data hiding that is good for security concerns. The in-depthtopic of Polymorphism will be discussed in later articles. Some of the advantages of OOPS include Reusability, Data Redundancy, Code Maintenance, Security, Design Benefits, Easy Troubleshooting, Better Productivity, Polymorphism Flexibility, and Problem-solving. Explanation: Java doesnt support all 4 types of inheritance.
