 > Think of a blog website where each post page follows the same layout with a header, footer, and main content area. While the header and footer remain consistent, the main content differs for each blog post. The Template View pattern encapsulates the shared layout (header and footer) in a base class while delegating the rendering of the main content to subclasses.

 > While not a classic Gang of Four pattern, Template View aligns closely with the Template Method pattern, applied specifically to rendering webpages or views. It defines a skeleton for rendering, delegating dynamic parts to subclasses while keeping the structure consistent.

 ## Programmatic Example of Throttling Pattern in Java
 
 In this Java example, we demonstrate throttling. A young human and an old dwarf walk into a bar. They start ordering beers from the bartender. The bartender immediately sees that the young human shouldn't consume too many drinks too fast and refuses to serve if enough time has not passed. For the old dwarf, the serving rate can be higher.
