Gain insights into software design patterns to create extensible, maintainable, and flexible code. Explore real-world examples in Java and enhance your problem-solving and architectural skills.

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.

<p>The literal meaning of <i>memento</i> is <i>an object kept as a reminder or souvenir of a person or an event</i>. The memento pattern <b><i>let's us capture the internal state of an object without exposing its internal structure so that the object can be restored to this state later</i></b>. In some sense we are saving a token or a memento of the original object and then recreating the object's state using the memento at a later time.
