The Factory design pattern is a creational pattern that provides a way to create objects without specifying the exact class of object that will be created. It allows for more flexibility and extensibility in the creation of objects.
public class MySQLConnection extends DatabaseConnection { @Override public void connect() { System.out.println("Connecting to MySQL database..."); } }
public class PostgreSQLConnection extends DatabaseConnection { @Override public void connect() { System.out.println("Connecting to PostgreSQL database..."); } } In this example, the DatabaseConnectionFactory class acts as a factory, creating and returning DatabaseConnection objects of different classes based on the databaseType parameter.
