Patterns in Java

Patterns (such as the famous GoF Design Patterns) are essential if you want to develop reliable and maintainable software according to the proven OO principles. To start with, patterns are frequently incorporated in existing frameworks, programming languages and class libraries: if you understand patterns, you will use these programming resources more efficiently. In addition to that, being able to recognize problem situations and to actively apply patterns to them is the key to a more robust design.

This course explains what patterns are, and gives a detailed discussion of the most common design patterns (the problem, the solution, the motivation, the usage examples). and their (subtle) relations and differences. We apply these patterns in an integrated Java exercise.
