Design Patterns in Java

✴ Design patterns are programming language independent strategies for solving the common object-oriented design problems. 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.✦
► To become a professional software developer, you must know at least some popular solutions (i.e. design patterns) to the coding problems.✦
