The Adapter patternis a common pattern, much like Singleton, Factory, and Decorator, you will see many examples of the Adapter pattern through the code, and one of the main benefits of using the Adapter pattern in Java is code reuse, making incompatible interfaces work together and loosely cou...
It’s powerful and can help resolve tricky problems and improve an application’s design. Also, Java has some built-in solutions to help implement this pattern; we’ll discuss them in the end. 2. Related Patterns Usually, the Pipeline pattern is compared to theChain of Responsibility. Pipelin...
In this example, the VideoConverterFacade acts as the Facade, providing a simplified interface for video conversion. It hides the complexity of the three subsystems (VideoLoader, VideoEncoder, and VideoSaver), making it easier for clients to interact with them through the unified convertVideo meth...
when an object should be able to notify other objects without making assumptions about who these objects are. In other words, you don't want these objects tightly coupled Typical Use Case: changing in one object leads to a change in other objects Real world examples: java.util.Observer St...
Observers (or listeners) watch for changes in the subject and react accordingly, making this pattern particularly useful in scenarios where a change in one part of the system needs to be communicated to multiple other parts. 1.2. Example The Observer Pattern is widely used in Java, particularly...
multiple sub-classes. This is the most widely used java design pattern because this pattern takes responsibility for instantiating a class from the client program to the functional class. This pattern is flexible in applying the Singleton pattern to the factory class or making the factory class ...
In plain words Memento pattern captures object internal state making it easy to store and restore objects in any point of time. Wikipedia says The memento pattern is a software design pattern that provides the ability to restore an object to its previous state (undo via rollback). ...
The benefits of using State pattern to implement polymorphic behavior is clearly visible. The chances of error are less and it’s very easy to add more states for additional behavior. Thus making our code more robust, easily maintainable and flexible. Also State pattern helped in avoiding if-el...
Using record patterns helps avoid such unnecessary casts, as well as, record components are directly accessed making the code more concise, clean, and readable. 3. Pattern Matching Pattern matching is referred to be the operation to take a type pattern (e.g. record pattern) and perform matchin...
Flyweight pattern implementation is not useful when the number of intrinsic properties of Object is huge, making implementation of Factory class complex. That’s all for Flyweight design pattern in java.
