Chapter 12, Problem 1D
Explanation of Solution
Object oriented design:
- A set of process that is involved in developing a set of classes for problem solving is called as object oriented design.
- It is considered as most powerful complement to the top-down design for developing a reliable, cost-effective software system.
- The goal of top-down design is developing set of black-boxes and its associated interfaces.
- A top-down design seeks for the function whereas the Object Oriented Design seeks for an Object.
Process of Object oriented design OOD:
There are many different ways to process OOD and they are as
- Look for object candidates.
- While considering a problem definition, the main goal is to define a set of objects that aids in solving the problem.
- The objects that are chosen are often described through nouns.
- The nouns present in the each problem statement are considered and underlined one by one based on the below mentioned factors.
- Identify instance variables.
- Based on the value possessed by the instance variable the instance variables are identified.
- Most of the instance variables are considered to have primitive value whereas some of them seem to have complex types...
