If you want to code DB-driven apps in Java you must learn two basic things:

1. To read exception messages. They are there for a reason: to tell you what the error was and provide hints about how to fix it.

2. To identify the different technologies you are using.

Said that, abc/sample/usermaster is not a valid database name in MySQL. Have you even installed MySQL Server in your computer?
