Object-oriented programming was formally introduced in the 1970's with the advent of Smalltalk. C++ took it mainstream in the 1980's, and Java carried it to the next level in the 1990's. Unfortunately, if you examine the vast majority of Java codebases, what you'll find is a bunch of C-style structs (a.k.a. JavaBeans) and functions. As these codebases grow, a number of design smells can potentially crop up, which in turn cripple our ability to respond to change. We need SOLID principles that we can apply to keep our software clean and malleable.
Robert C. "Uncle Bob" Martin identified several design smells in his book Agile Software Development: Principles, Patterns, and Practices:
We can reverse and in fact avoid these techniques by following the principles of SOLID software design:
• Single Responsibility
• Liskov Substitution
• Interface Segregation
• Dependency Inversion
You'll leave this session equipped to ferret out design smells and apply these principles on your next project.
