How do you know when to use design patterns?
Software Engineering and Design Patterns are exactly the same. They are simply common solutions to common problems. If you know the design patterns, then when you are working through a design, and particular part of a system requires something that fits a design pattern you have, then use it.
Is design patterns hard to learn?
Design patterns are a great concept that are hard to apply from just reading about them. Take some sample implementations that you find online and build up around them. A great resource is the Data & Object Factory page. They go over the patterns, and give you both conceptual and real world examples.
When should design patterns not be used?
If a problem has two solutions, one that fits in ten lines of code, and another one with hundreds of lines of code along with a pattern, please consider not using the pattern. Their presence isn’t a quality measurement.

Why is it important to learn design patterns in Java?
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. Advantage of design pattern:
How do you recognize design patterns?
Design patterns are best recognized as a high-level issue; one that is only relevant if you have the experience necessary to recognize them as useful. It’s good that you recognize that they’re useful, but unless you’ve seen situations where they would apply, or have applied, it’s almost impossible to understand their true value.
What is the most important part of a design pattern?
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.
What are design patterns in C++?
Design patterns are programming language independent strategies for solving a common problem. That means a design pattern represents an idea, not a particular implementation. By using design patterns, you can make your code more flexible, reusable, and maintainable.
