Java Design Patterns

What is design mode Gang of Four (GOF)?

In 1994, four authors:Erich Gamma,Richard Helm,Ralph Johnson and John vlissides published a book entitled Design Patterns- Reusable object-oriented software elements, a book that pioneered the concept of design patterns in software development.

These authors are collectively referred to as Gang of Four (GOF). According to these authors, design patterns are based primarily on the following principles of object-oriented design:

• The program to an interface is not implemented.

• Facilitates the combination of inherited objects.

Use of design Patterns

Design patterns have two main uses in software development.

Common Platform for Developers

Design patterns provide standard terminology and are specific to applying a folded scene. For example, a singleton design pattern represents the use of a single object, so all developers who are familiar with a single design pattern will use a single object, and they can tell the other program is following a singleton pattern.
