Different Types of Design Patterns in Java
Design Patterns are widely used by software engineers. A design pattern is a well-defined solution to a frequently encountered software problem. Java design patterns are classified into three types: creational, structural, and behavioral. You can learn more about Java design patterns from an online Java Full Stack training in Kochi and gain a strong base in Java Full Stack development.
Rather than instantiating objects directly using the new operator, these design patterns give a mechanism to construct things without obscuring the logic. This allows the software more flexibility in determining which objects are required for a specific use case.
There are different sorts of creational design patterns.
- Factory Pattern
- Abstract Factory Pattern
- Singleton Pattern
- Builder Pattern
- Prototype Pattern
Structural design patterns
Structural design patterns are focused with the composition of classes and objects to construct large structures. By recognizing the relationships, structural design patterns simplify the architecture. These patterns are concerned with how classes inherit from one another and how they are built from other classes.
There are seven different types of structural design patterns.
- Adapter Pattern Changing one interface into another to accomplish the demands of the client.
- Bridge Pattern Separation between abstraction (interface) and implementation
- Composite Pattern Allowing clients to act on object hierarchies.
- Decorator Pattern Dynamically adding functionality to an item.
- Facade Pattern Providing an interface to a group of interfaces.
- Flyweight Pattern Sharing an object allows it to be reused.
- Proxy Pattern Representing a different object.
Behavioral design pattern
Behavioral design patterns are concerned with object interaction and responsibility. These patterns boost the flexibility with which this communication is carried out.
- Chain of responsibility
- Command Pattern
- Interpreter Pattern
- Iterator Pattern
Design patterns use object arrangements and some object-oriented principles to solve typical software development design problems. Applying design patterns to your design and development will enhance object reuse and make software updates easier.
