Question

I’ve been learning the adapter and facade design patterns for an upcoming junior development role i’m applying for, as i’m expecting to be asked what i know about the pattern and times i’ve used it. While the pattern itself seems straight forward – i’m struggling to think of a practical use i could use it for in a personal project.

So can anyone suggest an idea for a use for it within a small personal project?

Also does the pattern appear anywhere within the Java API?

Answer 1

For uses in Java API of design patterns, look at this question.

Quoting Wikipedia:

In computer programming, the adapter
pattern (often referred to as the
wrapper pattern or simply a wrapper)
is a design pattern that translates
one interface for a class into a
compatible interface.

So you will use it quite rarely. It is just adapting two incompatible interfaces.

And remember when you don’t need a design pattern, just don’t use it. Only because it is written in the big books, it doesn’t mean it serves all your needs and you must follow it blindly.
