JavaSpecialists – Java Design Patterns 2022-2

Java Design Patterns, How you can get Java design patterns to do exactly what you want and accelerate your software career in less than 1 week. Like so many programmers of my generation, I started coding in BASIC. After a short foray into Turbo Pascal, my university led me gently to C.
Professor MacGregor then introduced C++. His lectures were ramblings in a thick Glasgow accent with matching handwriting. Stroustrup’s writing became my bible. All through my university education, I struggled to rid myself of the bad habits endowed by years of BASIC and C. Polymorphism? No, I used switch statements and multi-conditional ifs. We learn more by doing than by listening. Every pattern is followed by exercises that we solve to improve our understanding of the pattern. For each exercise we have model solutions and a detailed walkthrough, where I show you the thought process in solving the exercise. Some of the exercises are hard. Others easier. The patterns are sourced from both the original Gang-of-Four book by Erich Gamma et al, in addition to proceedings from the Pattern Language of Program Design conferences. They are categorized into behavioral (B), structural (S) and creational (C) patterns. Here is the golden order that we follow through this maze of patterns

What you’ll learn

Using Patterns in the JDK: Practical application of patterns using existing classes from the Java Development Kit.
Refactoring existing designs into patterns: Transform bad designs into more maintainable code by applying design patterns.
Fun fun fun: Not all exercises are entirely practical. Lab rats are reanimated with memento and rappers made to sing with the adapter pattern.
