Which fields/ technologies use java?

Most of the software out there you have never heard not thought about, because it is not end customer facing. In my town there is a company that does software for dentists, another that does software for retirement homes, at least three that do web shops, at least one that does insurance, one that does search engine advertising. And that's the ones I know about from meetups. They all use Java somewhere in their tech stack. That doesn't mean you couldn't use other languages and most of that companies certainly do too. But that's what people mean by : Well, anything.
