In object-oriented programming, a factory is an object or a method that creates and returns other objects. The factory pattern is used to encapsulate the creation of objects, making it easier to modify or extend the creation process without affecting the rest of the application.

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. com.swfp.factory

public abstract class DatabaseConnection { public abstract void connect(); } In object-oriented programming, a factory is an object

Suppose we have a system that needs to create different types of database connections, such as MySQL, Oracle, and PostgreSQL. We can use a factory pattern to create a database connection object without specifying the exact class of object that will be created. such as MySQL

public class MySQLConnection extends DatabaseConnection { @Override public void connect() { System.out.println("Connecting to MySQL database..."); } }
