Our course covers 23 basic patterns that are generally considered to be the foundation for all other patterns. During the course participants will have the opportunity to practice these patterns with the help of case studies and exercises.

The course deals with the concept of refactoring as a way of preventing software rot. The course describes various smells indicating that a code needs refactoring, explains which refactoring types best suit specific situations, and describes the work of refactoring in detail through analyzing concrete real-life cases.

The training explores new design patterns and language idioms, showing how to make the most of features ranging from generics to enums, annotations to autoboxing.

The seminar teaches the SOLID design principles with practical examples and builds together with an exercise that is continued throughout the training: writing an application in 5 sprints. The exercise shows how good design keeps the complexity down while adding business features and technical tasks. In the process, design patterns will be deployed and refactoring will be performed to achieve elegant solutions.
