That means a design pattern represents an idea, not a particular implementation. By using the design patterns you can make your code more flexible, reusable, and maintainable. It is the most important part because java internally follows design patterns. Categorization of design patterns: Basically, design patterns are categorized into two parts: Core Java (or JSE) Design Patterns. JEE Design Patterns. Core Java Design Patterns In core java, there are mainly three types of design patterns, which are further divided into their sub-parts: 1.Creational Design Pattern Factory Pattern Abstract Factory Pattern Singleton Pattern Prototype Pattern Builder Pattern. 2.
