Command pattern is a behavioral design pattern which is useful to abstract business logic into discrete actions i.e. commands. It motivates loose coupling.
Strategy design pattern is behavioral design pattern where we choose a specific implementation of algorithm or task in run time – out of multiple other implementations for same task.
Template method design pattern is widely accepted behavioral design pattern to enforce some sort of algorithm (fixed set of steps) in the context of programming. It defines the sequential steps to execute a multi-step algorithm and optionally can provide a default implementation as well (based on requirements).

Design patterns are used to solve the problems which occur in a pattern, we all know that, right? Also we know that behavioral design patterns are design patterns that identify common communication patterns between objects. One of such behavioral patterns is visitor pattern, which we are going to learn about in this post. If you […]
The Chain of Responsibility is known as a behavioral pattern. The main objective of this pattern is that it avoids coupling the sender of the request to the receiver, giving more than one object the opportunity to handle the request. The core logic defined by GoF is : “Gives more than one object an opportunity […]
