Factory pattern and Strategy pattern might create a confusion if you are using them for the first time. Atleast I was confused, so I tried to analyze the two patterns further.

Let’s relook at the two examples which we used for factory and strategy pattern.

Car Factory- A factory for creating Sedan or Hatchback car at the run time based on user need.

Tax Calculator- To pick at run time which type of tax to be calculated (Indian or German).

The difference lies in the usage of two examples above. In first example we are creating object of something, so we can conclude factory pattern is a creational pattern. In second example it is clear we are trying to achieve a goal / execute a method based on input, hence strategy pattern is an operational pattern.
