I'm a not really a creative person and I would like to ask if someone knows a good example for the use of the Template Method? It should have a technical use like for example a sorting algorithm and not be very basic like a burger maker. Thank you in advance! 🙂

Template Method

Template Method is a behavioral design pattern that defines the skeleton of an algorithm in the superclass but lets subclasses override specific steps of the algorithm without changing its structure.

#

good example would be JDBC template

#

where it goes through same steps: acquires connection from pool (or creates, if no connection pool), creates Statement according to sql query, executes the query. And all you need is to provide RowMapper object, that will map each row of result to the java object.

#

(in case that sql query selecting something)
