# Design Patterns Revisited

Design Patterns are standard solutions to common design problems in object-oriented applications. They act as guidelines that can be used to solve recurring design problems in your code. If you have been in the software industry for a while, it is possible that you have already implemented some of these  patterns without realizing it.

Note that design patterns are not ready-to-use code solutions. They describe or suggest how the solution should look like.
