package org.learn.david.creational.factorymethod;
Factory Method is a creational design pattern that provides an interface
for creating objects in a superclass, but allows subclasses to alter the
type of objects that will be created.
package org.learn.david.creational.builder;
package org.learn.david.creational.builder2;
Builder is a creational design pattern that lets you construct complex
objects step by step. The pattern allows you to produce different types and
representations of an object using the same construction code.
package org.learn.david.creational.AbstractFactory;
Abstract Factory is a creational design pattern that lets you produce families
of related objects without specifying their concrete classes.
package org.learn.david.creational.Singleton;
Singleton is a creational design pattern that lets you ensure that a class has
only one instance, while providing a global access point to this instance.
package org.learn.david.structural.adapter;
Adapter is a org.learn.david.structural design pattern that allows objects with
incompatible interfaces to collaborate.
package org.learn.david.structural.bridge.nobridge; - Without Bridge Pattern
package org.learn.david.structural.bridge.bridge; - Bridge Pattern used
Bridge is a structural design pattern that lets you split a large class or a set
of closely related classes into two separate hierarchies—abstraction and
implementation—which can be developed independently of each other.
package org.learn.david.structural.composite;
Composite is a structural design pattern that lets you compose objects into
tree structures and then work with these structures as if they were individual objects.
package org.learn.david.structural.decorator;
Decorator is a structural design pattern that lets you attach new behaviors
to objects by placing these objects inside special wrapper objects that contain
the behaviors.
package org.learn.david.structural.facade;
Facade is a structural design pattern that provides a simplified interface to a
library, a framework, or any other complex set of classes.
package org.learn.david.structural.flyweight;
Flyweight is a structural design pattern that lets you fit more objects into the
available amount of RAM by sharing common parts of state between multiple objects
instead of keeping all of the data in each object.
package org.learn.david.structural.proxy;
Proxy is a structural design pattern that lets you provide a substitute or placeholder
for another object. A proxy controls access to the original object, allowing you to
perform something either before or after the request gets through to the original object.
package org.learn.david.behavioral.chainofresponsibility;
Chain of Responsibility is a behavioral design pattern that lets you pass requests along
a chain of handlers. Upon receiving a request, each handler decides either to process the
request or to pass it to the next handler in the chain.
package org.learn.david.behavioral.command;
Command is a behavioral design pattern that turns a request into a stand-alone object that
contains all information about the request. This transformation lets you pass requests as
a method arguments, delay or queue a request’s execution, and support undoable operations.
package org.learn.david.behavioral.iterator;
Iterator is a behavioral design pattern that lets you traverse elements of a collection without
exposing its underlying representation (list, stack, tree, etc.).
package org.learn.david.behavioral.mediator;
Mediator is a behavioral design pattern that lets you reduce chaotic dependencies between objects.
The pattern restricts direct communications between the objects and forces them to collaborate only
via a mediator object.
package org.learn.david.behavioral.memento;
Memento is a behavioral design pattern that lets you save and restore the previous state of an object
without revealing the details of its implementation.
package org.learn.david.behavioral.observer;
Observer is a behavioral design pattern that lets you define a subscription mechanism to notify multiple
objects about any events that happen to the object they’re observing.
package org.learn.david.behavioral.state;
State is a behavioral design pattern that lets an object alter its behavior when its internal state
changes. It appears as if the object changed its class.
package org.learn.david.behavioral.strategy;
Strategy is a behavioral design pattern that lets you define a family of algorithms, put each of them
into a separate class, and make their objects interchangeable.
package org.learn.david.behavioral.templatemethod;
Template Method is a behavioral design pattern that defines the skeleton of an algorithm in the
superclass but lets subclasses override specific steps of the algorithm without changing its structure.`
package org.learn.david.behavioral.visitor;
Visitor is a behavioral design pattern that lets you separate algorithms from the objects on which they operate.
