Should I know design patterns?

What are the essential elements of a design pattern?

Design patterns have 4 essential elements:Pattern name: increases vocabulary of designers.Problem: intent, context, when to apply.Solution: UML-like structure, abstract code.Consequences: results and tradeoffs.

How are patterns used in everyday life?

How do you describe a design pattern?

In software engineering, a design pattern is a general repeatable solution to a commonly occurring problem in software design. A design pattern isn’t a finished design that can be transformed directly into code. It is a description or template for how to solve a problem that can be used in many different situations.

What is design pattern with example?

Design patterns provide a standard terminology and are specific to particular scenario. For example, a singleton design pattern signifies use of single object so all developers familiar with single design pattern will make use of single object and they can tell each other that program is following a singleton pattern.
