This course helps you become a better software engineer by mastering design patterns in software engineering.

Being good at problem-solving is one thing but to take your career to the next level, one must know how complex software projects are architected. Software design patterns provide templates and tricks used to design and solve recurring software problems and tasks.  Applying time-tested patterns result in extensible, maintainable and flexible high-quality code, exhibiting superior craftsmanship of a software engineer. Being well-versed in knowledge of design patterns allows one to spot brittle and immature code from miles away. The course goes to great lengths to lay bare the esoteric concepts of various design patterns before the reader and is replete with real-world examples and sample code.
The readership for this course is expected to be familiar with some object orientated language. The course examples and snippets are written in the Java language but folks with experience in other OOP languages should easily be able to follow the discussion and code intent.

Software Design Patterns: Best Practices for Software Developers

<p>A template can be thought of as a general or abstract structure that can be customized for specific situations. You may have used a <i>template</i> for writing your resume. The template would define the overall structure of the document and leave the details to be added in by the template user. The template method pattern is similar, it defines the skeleton or steps of an algorithm but leaves opportunities for subclasses to override some of the steps with their own implementations.</p>

<p>Formally, the pattern is defined as <b><i>allowing subclasses to define parts of an algorithm without modifying the overall structure of the algorithm.</i></b></p>

This lesson discusses how algorithms with multiple steps can be made configurable by allowing subclasses to provide behavior for some of the steps.
