Any objection?

Object Oriented Programming

5. COPY What is OOP? http://dataq.lecture.ub.ac.id/
it’s a new way of thinking in programming
Object-oriented programming relates the programming activity of modelling or simulation.
Objects are identified by a correspondence with the objects found in the real world and used to model those operations.

6. COPY Thinking in OOP http://dataq.lecture.ub.ac.id/
I have some function and unique serial number
Hi, I'm an “object” called calculator
So calculator is a “class”
We call it “Attribute and Method”
We call it “object composition”
I have so many friend like me but with different serial number.
We call it “instance”
I also builded from some other objects

7. We call it “inheritance”
Thinking in OOP
COPY
I can calculate addition, subtraction , multiplication, division and other mathematics function
Display, button, battery, box, processor are the components that build me.
We call it “inheritance”
I have some child, they are scientific calculator, programmer calculator and statistics calculator. They inherit my features but also have several improvement that I didn’t have.

8. COPY Thinking in OOP http://dataq.lecture.ub.ac.id/
Let me introduce some of my child
Hi, I am scientific calculator
Hi, I am programmer calculator
Some of our button is same, but it can behave in the different way.
We call it “polymorphism”

9. We call it “encapsulation” We categorize this function as
Thinking in OOP
COPY
We call it “encapsulation”
I bet you didn't how the process inside me.
But don’t worry, You can give me command by pressing each of my button.
We categorize this function as
“public method”
You know what will happen if you press each of my button, right?
We categorize
this button as
“public attribute”

10. It will help you to make the system simple and clean
Set this as our mindset!
COPY
Treat a problem like the real object in the real world!
Visualize this object in the virtual world
Attributes and methods that user don’t need to know should be encapsulate!
List the attributes and methods that visible to the user
Make class hierarchy for class that have similar function
It will help you to make the system simple and clean

11. COPY Let's practice! http://dataq.lecture.ub.ac.id/ I have a “tamiya”.
Do you know tamiya?
This is tamiya!
I want to simulate this tamiya in the computer. So I can decide what kind of part that I need to change if I want to boost the performance.

12. COPY Let's practice! http://dataq.lecture.ub.ac.id/
Can you help me to build an OOP program design? I need a clean an simple program that can be extend if I need some improvement or I have to simulate the other type of tamiya.
Maybe you start by listing the object that involve in this simulation? And of course after that you need to listing the attributes and methods for each object.

13. COPY Group assignment Its time to learn JAVA programming!!!
Its time to learn JAVA programming!!!
Study basic JAVA programming language like print, read input, if, do, for, define a class and making an instance.
In the next meeting we will have a group quiz! (^.^)
