How to install JDBC driver for postgres?

Question

PostgreSQL

I read a bunch of tutorials, but I still don’t understand what needs to be written in the classpath and with what parameters. And where to throw the jar driver, everywhere they write that in jre / lib / ext, but I don’t have a jre directory in jdk.

Answer 1

Prescribe in SR - directly the path to the file, for example. Without any parameters.
