how does inheritance promote software reusability

Any real world and well-architected application will constantly combine both of these concepts to gain as much reuse as possible. 0000378740 00000 n 3 • Using inheritance to promote Objectives software reusability 0000374172 00000 n This practice is usually called implementation inheritance. So, to me, a concrete Cache - for example a MemcacheCache implementation - extending from an abstract Cache base class is a very sane thing to do. 0000378318 00000 n 0000005054 00000 n Get 1:1 help … So, Java removed the problems that come with multiple inheritance (the famous diamond problem) but also the advantages that come with it such as code reusability. 0000374087 00000 n As an example, there is a design pattern designed to compose zero-or-more comparable objects so that they can be manipulated as one (Composite). 0000016984 00000 n 0000009256 00000 n CSC 330 OO Software Design 4 Main Benefit - code reuse: No need to replicate class methods (the subclass can inherit those of the superclass). Objectoriented programming helps in achieving the concept of reusability through different types of inheritance programs, which further help in developing reusable software modules. Inheritance helps in the software re-usability by using the existing components of the software to create new component. To access superclass members with super. Example: class BaseClass { public void hello() { Console.WriteLine("Parent's Hello Method"); } } class ChildClass : BaseClass { public void World() { Console.WriteLine("Child's World Method"); } } 0000012552 00000 n 0000003455 00000 n 0000006149 00000 n 0000017360 00000 n 0000074690 00000 n The notions of superclasses and subclasses. Question: Discuss The Ways In Which Inheritance Promotes Software Reuse, Saves Time During Program Development, And Helps Prevent Errors. 0000330678 00000 n To use access modifier protected to give subclass methods access to superclass members. Inheritance in Java is a mechanism in which one object acquires all the properties and behaviors of a parent object. Of these projects many are now based on solid object-oriented philosophies. To use keyword extends to create a class that inherits attributes and behaviors from another class. 2 Answers. 0000378761 00000 n When we solve a problem we try to apply the solution to similar problems because that makes our work easy and simple. 0000005136 00000 n 0000372813 00000 n 12.4 Discuss the ways in which inheritance promotes software reuse, saves time during program development and helps prevent errors. 0000074856 00000 n In object-oriented programming, inheritance is the mechanism of basing an object or class upon another object (prototype-based inheritance) or class (class-based inheritance), retaining similar implementation.Also defined as deriving new classes (sub classes) from existing ones such as super class or base class and then forming them into a hierarchy of classes.

Instead, code reusability defines the methodology you can use to use similar code, without having to re-write it everywhere. The notions of superclasses and subclasses. Recently, however, some commentaries suggest OOP has not lived up to expectations [Ude94]. •reusability of code.
