There are three types of Design Patterns: 1. Creational Design Patterns in Java Creational design patterns focus on efficient and flexible object creation. They decouple the system from the process of instantiating objects, making the code more maintainable, adaptable and independent of how objects are constructed or represented.

The pattern allows you to produce different types and representations of an object using the same construction code. Provides an interface for creating objects in a superclass, but allows subclasses to alter the type of objects that will be created. Lets you copy existing objects without making your code dependent on their classes.

Modern Java features, such as lambda expressions, method references, and functional programming, can be leveraged to simplify the implementation of design patterns. For example, the Strategy pattern can be implemented more concisely using lambda expressions, making the code more expressive and easier to read.

This exploration delves into identifying and illustrating various design patterns as found in the Java JDK. Creational patterns deal with object creation mechanisms, aiming to increase flexibility and reusability.
