java programming and database connection [closed]

I have a problem that is making me miserable. It is as follows:

But the problem is that the program only runs on the machine perfectly on the machine where the database is installed, I would like to know how to ensure that the application will continue to save data without however having the database installed.

Basically I need to know somehow how to load the database along with my application. package bie.trabalho.utilitarios;
