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>Composite literally means <b><i>made up of various elements or parts</i></b>. The pattern allows you to treat the whole and the individual parts as one. The closest analogy you can imagine is a tree. The tree is a <i>recursive</i> data-structure where each part itself is a sub-tree except for the leaf nodes. The root is the top-level composite and its children are either composites themselves or just leaf nodes. The leaf itself can be thought of as a tree with just a single node.
</p>
<p>Formally, the composite pattern is defined as <b><i>composing objects into tree structures to represent part-whole hierarchies, thus letting clients uniformly treat individual objects and composition of objects.</b></i></p>

<p>The pattern allows the clients to ignore the differences between the whole and the part.</p>
