OOPS
- 1. SOFTWARE ENGINEERING PRESENTED BY : PRATIKSHA GARTAULA
- 2. OOPS Object-oriented programming (OOP) is a computer programming model that organizes software design around data, or objects, rather than functions and logic. An object can be defined as a data field that has unique attributes and behavior. OOP can be used for manufacturing system simulation software.
- 3. OOPS What are the main principles of OOP? Encapsulation Abstraction Inheritance Polymorphism
- 4. OOPS Encapsulation : This principle states that all important information is contained inside an object and only select information is exposed Abstraction : Objects only reveal internal mechanisms that are relevant for the use of other objects, hiding any unnecessary implementation code. Inheritance : Classes can reuse code from other classes. Relationships and subclasses between objects can be assigned, enabling developers to reuse common logic while still maintaining a unique hierarchy Polymorphism: Objects are designed to share behaviors and they can take on more than one form. The program will determine which meaning or usage is necessary for each execution of that object from a parent class, reducing the need to duplicate code.
- 5. Class In object-oriented programming, a class is a blueprint for creating objects (a particular data structure), providing initial values for state (member variables or attributes), and implementations of behavior (member functions or methods). A class is a group of objects which have common properties. It is a blueprint or prototype for creating objects. Class members are access modifiers.
- 7. Object An object is an instance of a class. Any entity that has state and behavior is known as object. For example a chair,pen.
- 8. Access Modifier An access modifier is a keyword in object-oriented programming languages like Java that defines the scope and visibility of classes, methods, fields, and constructors within a program. Public Access Modifier We can access the public modifier from anywhere. We can access public modifiers from within the class as well as from outside the class and also within the package and outside the package.
- 9. Access Modifier Private Access Modifier We can access the private modifier only within the same class and not from outside the class. Default Access Modifier We can access the default modifier only within the same package and not from outside the package. And also, if we do not specify any access modifier it will automatically consider it as default.
- 10. Access Modifier Protected Access Modifier We can access the protected modifier within the same package and also from outside the package with the help of the child class. If we do not make the child class, we cannot access it from outside the package. So inheritance is a must for accessing it from outside the package.
