Final Review
- Be very familiar with c# syntax
- Basic object types (int, bool, string)
- Conditional and Branching statements
- Arrays and Generics ie List
- Understand Classes and Inheritance.
- Use some advanced class features such as abstract classes and virtual methods that are overridden
- Understand class relationships
- Is A
- Has A
- Uses A
- Understand Encapsulation, Abstraction and Polymorphism
- Abstraction
- Each class should abstract its behavior in order to increase usability, reuse, and organization.
- Encapsulation
- Each class should contain all of the properties and methods it needs. It should only expose what is necessary to outside classes.
- Polymorphism
- many forms, same code interface but interchangeable classes
- Be able to read and create UML Diagrams
- Be able to recognize and use simple design patters
The final will be consist of two sections the writtens section and the practical section. The practical section will be open everything excpet open mouth (yes open note open book open web). You will not be ablt to use any of theese resources during the written section.
