Lecture 1

Object Oriented Programming : why?

What already exists: Procedural programming

• A lot of code to make pieces of program work together
• A technical approach that lessen the code comprehension
• Big programs are difficult to maintain

Object Oriented Programming : (human) definition

The definition of the Object Oriented Programming, is that this kind of programming uses object

This said, what is an Object?

• Objects are a conceptual representation of existing things
• This makes the programming easier to approach because things are clearer for the developper

Object Oriented Programming : tools

• IntelliJ IDEA is one of the most popular Java development environments
• Provides intelligent code completion and analysis
• Excellent refactoring and debugging tools
• We'll use the Community Edition (free and open-source)
