CHAPTER 1

1. PROGRAMMING TECHNIQUE

   • unstructured programming
     • computer instruction algorithm
     • produce spaghetti code (unstable source code)
     • apps : JOSS, FOCAL, COBOL
   • procedural programming
     • Top down design / sequence statement
     • loops, assignment
   • object oriented programming
     • method programming based on hierarchy classes
     • create class, coop with create object
     • Java support OOP (OOP approach)
     • to organize complex program easily

2. FEATURES OF OOP

   • inheritance
     • class derives of properties of another class
   • polymorphism
     • ability object to take many form
     • eg : buttons on remote control used same method, receive other output
   • data abstraction
     • concept represent only essential feature of data without including the non essential details (already showed)
   • encapsulation
     • mechanism (program) of wrapping up of data & method (operate data) into single unit (class diagram/UML Class Diagram

3. ADVANTAGES OF OOP

   • simple
     • software object are treated similar to real object
   • data security
     • each object can access only essential members (access specifier)
   • reusability
     • program can be assembled (inheritance)
   • modularity
     • software project can split up into small pieces (class)

4. TYPE OF OBJECT ORIENTED

   • OOA
     • in documentation
   • OOD
     • process defining component interface : object, class, attribute
   • OOAD
     • combine analysis & design
