Connection connection = DriverManager.getConnection("jdbc:mysql://localhost:3306/mydatabase", "username", "password");
// Create a statement
Statement statement = connection.createStatement();
// Create tables
String createTableQuery = "CREATE TABLE Customers (
id INT PRIMARY KEY AUTO_INCREMENT,
name VARCHAR(100) NOT NULL,
email VARCHAR(100) NOT NULL UNIQUE,
address VARCHAR(200)

statement.executeUpdate(createTableQuery);
// Close the connection
connection.close();
