The Bridge pattern lets you split the monolithic class into several class hierarchies . After this, you can change the classes in each hierarchy independently of the classes in the others. This approach simplifies code maintenance and minimizes the risk of breaking existing code.
Read moreWhy do we use bridge patterns?
Bridge is used when we need to decouple an abstraction from its implementation so that the two can vary independently . This type of design pattern comes under structural pattern as this pattern decouples implementation class and abstract class by providing a bridge structure between them.
Read moreWhat is Bridge pattern C++?
Bridge is a structural design pattern that divides business logic or huge class into separate class hierarchies that can be developed independently . One of these hierarchies (often called the Abstraction) will get a reference to an object of the second hierarchy (Implementation).
Read moreWhat is the Bridge pattern example?
Example. The Bridge pattern decouples an abstraction from its implementation, so that the two can vary independently. A household switch controlling lights, ceiling fans, etc. is an example of the Bridge. The purpose of the switch is to turn a device on or off.
Read moreWhat is the Observer pattern good for?
The Observer pattern suggests that you add a subscription mechanism to the publisher class so individual objects can subscribe to or unsubscribe from a stream of events coming from that publisher .
Read moreWhat is the Observer method?
The observer method is a Behavioral design Pattern which allows you to define or create a subscription mechanism to send the notification to the multiple objects about any new event that happens to the object that they are observing . The subject is basically observed by multiple objects.

Example of singleton classes is Runtime class, Action Servlet, Service Locator . Private constructors and factory methods are also an example of the singleton class.
