Object Oriented Programming
Karten in diesem Stapel (10)
- 1Object Oriented Programming OOPA program consists of objects.
Each object has its own data(attributes)
and operations/functions on that data(methods).
Objects interact with one another.
All processing is done by objects. - 2A classIs a blueprint for an object.
Defines attributes and methods which has the common characteristics and behaviours of objects. - 3EncapsulationAttributes and methods are wrapped into a single entity. (So basically attributes and methods are stored in a super class/ parent class instead of having it in every object )
- 4Information hidingAn object's attributes are hidden(private).
Its attributes are accessed and changed only through the object's methods.
Methods are required to set(setters) and retrieve(getters) an object's attributes. - 5InheritanceSub-classes uses attributes and methods of its superclass
- 6PolymorphismImplemented through overriding superclass methods
- 7Association - CompositionIf the container destroyed, objects remain
- 8Association - AggregatingIf the container destroyed, objects is destroyed as well
- 9Interface1. A collection of methods with no implementation(no result).
2. So it is a set of public method.
3. Reduce implementation specifics and made code more reusable - 10Advantage of OOP1. Extensive planning so better design
2. Source codes are written and maintained independently to other subjects.
3. Programmers can use exists object without knowing how it implemented
