QUESTIONS AND ANSWERS VERIFIED A+
◉ State Diagrams
Answer: - Used to show how objects respond to different service
requests and the state transitions triggered by these requests.
- State diagrams are useful high-level models of a system or an
object's run-time behavior.
- Don't need a state diagram for all objects in the system
◉ Interface Specification
Answer: - Object interfaces have to be specified so that the objects
and other components can be designed in parallel.
- Designers should avoid designing the interface representation but
should hide this in the object itself.
- Objects may have several interfaces which are viewpoints on the
methods provided.
, - The UML uses class diagrams for interface specification but Java
may also be used.
◉ Design Patterns
Answer: - A design pattern is a way of reusing abstract knowledge
about a problem and its solution.
- A pattern is a description of the problem and the essence of its
solution.
- It should be sufficiently abstract to be reused in different settings.
- Pattern descriptions usually make use of object-oriented
characteristics such as inheritance and polymorphism.
◉ Design Pattern Elements
Answer: 1) Name: A meaningful pattern identifier
2) Problem Description
3) Solution Description: Not a concrete design by a template for a
design solution
