Can I send an email in java to an account, and if I can, how can I do it?

Answer 1

Yes, you can. It's quite easy if you use a library.
This is a tutorial where Maven is used to manage the dependency to the library, but you could as well download the jar and put it on the build path to use it.
I don't know your learning level, so if you have further questions just ask.

Answer 2

Maven is a build/dependency management system.
If you are not familiar with it, it's better to manually download the jar for now.
