How To Connect To Xampp Server And Create New Database

The Source code below checks if the database name provided is found in the server. If the name is not found then, a new database with that name is created. Before creating or checking for existing database , first, am loading jdbc driver (Mysql connector/j) , Also you need to ensure that you are connected to the server by entering correct login credentials. Once connected, you can send queries to the server. Am using xampp localhost (mysql database,apache server ,phpmyadmin) in this guide.

Output When The Database Is Found.

run:
Jdbc Driver loaded successfully
Connected To Server Successfully
Database Found
