Java – what does “reference implementation” mean?

I'm trying to learn the cachedrowset in Java, and I'm reading some tutorials about it

for example

Who can please be kind and explain this?

Please note that I found some definitions on the Internet that are too vague for me

Solution

It means that the implementation of the specification of the concept should be demonstrated In most cases, it is implemented by the same person / company as the design specification

You can think of specifications as standards that allow other possible implementations to be compatible with the rest of the world And the reference implementation of proof of concept software should show how to do this and encourage others to create their own implementation

In the JDBC context, it means that some interfaces (cachedrowset) specify some methods, and the reference implementation of these interfaces is completed in sun / oracle
