What is an object?
  • object=entity
  • objects=attributes+services
  • Data: the properties or status  <  Operations: the functions
 
Mapping
  • From the problem space to the solution one.
C++ version:
 1 class Point3d{
 2 
 3 public:
 4 
 5     Point3d(float x,float y,float z);
 6 
 7     print();
 8 
 9 private:
10 
11     float x;
12 
13     float y;
14 
15     float z;
16 
17 };
18 
19 Point3d a(1,2,3);
20 
21 a.print();

 


 What is object-oriented
  • A way to organize
    • Designs
    • Implementations
  • Objects,not control or data flow, are the primary focus of the design and implementation
  • To focus on things,not operations.
