Q&A Highlights
The Q&A session during the Tech Connect Forum was vibrant and filled with insightful discussions.
- What are design patterns?
Design patterns are reusable templates or descriptions for solving common software design problems.
They are not finished designs that can be directly turned into code.
There are several types of design patterns, including:
Creational
These patterns are used for class instantiation and object creation. They can help increase flexibility and reuse existing code.
Examples include factory method, abstract factory, builder, prototype, and singleton.
Structural
These patterns are used to create more complex systems and organize code. They can help make code more modular and reusable.
Examples include the composite pattern, the decorator pattern, and the facade pattern.
Behavioral
These patterns are used to address how classes and objects communicate and interact with each other.
They focus on how objects work together to achieve certain functions or behaviors.
They contribute to the overall structure defined by the architecture pattern.
