Probably something related to Java

Which is an island. So who put the factory onto Jawa/Indonesia?

A dubious analogy.

Factories are places for the mass production of identical or nearly identical widgets.

There are some kinds of mass produced software, like the low value apps that lots of businesses want to have for some reason and that should have been websites instead.

But actual progress comes from software that isn't mass produced. So choose your ambitions wisely.

like a play-doh factory but more sweaty

A compiler.

Nope, a "gang of four" pattern from the book on architecture patterns.

And still, like the other commentator said, a dubious analogy. I found the dubious analogies prevalent inb software harmed my understanding.

Some would say "Gang of four" and "Design patterns" and "OOP" are all marketing BS
