The Observer pattern defines a one-to-many dependency between objects, so that when one object changes state, all its dependents are notified and updated automatically. This is useful when we want to decouple the sender of a notification from its receivers. The Mediator pattern defines an object that encapsulates how a set of objects interact. The Interpreter pattern provides a way to interpret sentences in a language and execute them.

In the early years of the 21st century, California reached the status of a “minority-majority state”—one in which the combined population of minorities exceeds the majority population. Los Angeles county has the largest Hispanic (the term Latino is also used in southern California), Asian, and Native American populations of any county in the United States. Compton and Inglewood, which once had African American majorities, have become predominantly Latino. The main links connecting downtown and the suburbs are the famed Los Angeles freeways, which spread throughout the region in a vast network of concrete ribbons. Some roads cross the Los Angeles River, which appears in the guise of a huge, cement-lined flood-control channel. The mountains and their steep-walled canyons are lined with shrubbery, grass, and occasional houses.

Development and publication history
Cape Cod architecture is one of the most iconic American house styles. Named after the coastal Massachusetts region, where this architecture is ubiquitous, it is actually based on a British Georgian style from the 18th century. Transposed to the American colonies, the style has been simplified and rendered practical for local materials and climates. Bungalows commonly have wide gabled roofs that extend over large front porches, with large columns propping up exposed eaves.

Motorists glimpse some dramatic vistas; for example, a nighttime view of the San Fernando Valley from the Mulholland summit of the San Diego Freeway. In general, however, there is little to distinguish one community from another as viewed from the freeways. Cars and trucks move in solid masses, streaming steadily along at rooftop level through single-story residential areas, shopping strips, and malls.
By changing the object or class, we can change the algorithm used, the objects affected, or the behavior, while still retaining the same basic interface for client classes. Additionally, Design patterns are not a silver bullet and should not be used as a replacement for good software design principles. They should be used in conjunction with other software design principles such as SOLID and DRY. Patterns originated as an architectural concept by Christopher Alexander as early as 1977 (c.f. "The Pattern of Streets," JOURNAL OF THE AIP, September, 1966, Vol. 32, No. 5, pp. 273–278). They use inheritance to compose interfaces and define ways to compose objects to obtain new functionality. These patterns help solve common problems in how pieces of code share tasks, hide whay they do, and stay organized.

These patterns teach us how to combine the unique parts of a system in a way that’s easy to change or expand without affecting the entire system. Think of Creational Design Patterns as those secret Pizza recipes that Chef use. These patterns help us create objects in a smart and organized way, just like how a Chef makes a perfect Pizza every time. The Abstract Factory pattern provides an interface for creating families of related or dependent objects without specifying their concrete classes.
Larger garages were also required as an increasing number of households owned more than one vehicle. Long an almost exclusively Roman Catholic town, Los Angeles began receiving many Protestants and some Jews in the late 19th century. While most were short-lived and had narrow appeal, at least one gained vast influence.

They provide ways to create objects without exposing the creation logic to the client. The creational patterns include Singleton, Factory Method, Abstract Factory, Builder, and Prototype. Often prized by Hollywood stars and producers, these comfortable but charming homes are characterized by earthy styles, stucco exteriors, red-tiled roofs, exterior stairways, and verandas. Their key motif is the arch, as decorative edging, around windows or often framing an elegant entranceway or portico. They are based on a style originating with the Spanish colonials in the sixteenth century and re-popularized by the 1915 Panama-California Exposition.
It allows us to simply traverse the elements, without exposing the underlying implementation that may give rise to vulnerabilities. Proxy basically means an intermediatory between 2 entities, basically representing another object to restrict/control access to it. Some use cases would be when we require some initial work to be done before processing a request, or adding an additional functionality which not a part of system that lies beyond the proxy. The core component here is the “facade”, its nothing but a class that intercepts every call made by the client and delegate it to the sub-classes that have the capability to handle the request. Its like a security guard that coordinates the action of the underlying system.
This style is based upon British Colonial architecture dating from the 1600s to the mid-1700s. This was also the era of planned subdivisions like Hollywoodland (in upper Beachwood Canyon), Whitley Heights, and Outpost Estates. The construction boom ran out of steam when the U.S. stock market crashed in 1929. Since the 1980s, the city has taken significant steps to redevelop downtown by increasing housing stock, accommodating new recreational and cultural activities, and inviting pedestrian activity. Downtown’s greatest deficiencies are its large Skid Row area (sometimes called Central City East) and its lack of housing for middle- and lower-income families and the shops and amenities that make life agreeable at street level.
And its considered as a classic in modern software engineering literature. It categorized the software design patterns into – Creational, Structural, and Behavioral Design Patterns. While design patterns are a great way to solve common problems in software development, it’s important to understand that they are not a one-size-fits-all solution. There may be cases where a design pattern is not the best solution or where it needs to be modified to fit the specific situation.
Acquaintance is a weaker relationship than aggregation and suggests much looser coupling between objects, which can often be desirable for maximum maintainability in designs. They warn that the implementation of a subclass can become so bound up with the implementation of its parent class that any change in the parent's implementation will force the subclass to change. Furthermore, they claim that a way to avoid this is to inherit only from abstract classes—but then, they point out that there is minimal code reuse. It is just another layer of abstraction over the factory pattern which involves creation of multiple logically related objects from a factory class.
Typical detailing includes simple Greek or Roman-style columns or pediments and square chimney stacks. Due to their steeply raked roofs, the front elevation of these homes conceals the sides of the building. American Colonial homes are usually rectangular in shape, but homeowners often add extensions to the side or rear elevations. The next wave of construction in Los Angeles occurred during WWII as thousands of workers moved to the area to take jobs with defense contractors (Boeing, Lockheed, Douglas, et al.) as part of the war effort.
Most behavioral design patterns are specifically concerned with communication between objects. In software development, we build complex programs like puzzles made up of many pieces (objects or classes). Behavioral design patterns are like special instructions for how these puzzle pieces should talk to each other and work together. Design patterns can speed up the development process by providing proven development paradigms.[4] Effective software design requires considering issues that may not become apparent until later in the implementation. Freshly written code can often have hidden, subtle issues that take time to be detected; issues that sometimes can cause major problems down the road. Reusing design patterns can help to prevent such issues,[5] and enhance code readability for those familiar with the patterns.
Balconies and bay windows are other possible modifications features in more extensive examples of this style. The boom period for this type of housing was 1700 to 1850, and a revival took place from the 1920s to the 1950s. Simple to construct and to extend, the Cape Cod style became popular throughout the US, particularly in the post-war era when the US government launched mortgage programs for returning servicemembers. A modern variant might include gabled dormers on the upper floor and decorative porticos with Greek or Roman-style columns. The architecture of that region, which spread quickly throughout New England, reflects this climate.
Low-pitched gabled roofs are an identifying feature of these homes, which tend to consist of a single floor spread out over a comparatively large floor plan. They are generally asymmetrical in layout and feature large front porches and exposed wooden structural elements. Asymmetry of design is a key feature, with idiosyncratic and cozy room layouts, often built around a central chimney. Front-facing gables sometimes incorporate a catslide roof, where a curving interior slope contrasts with steep, straight eaves on the outside.
