What Is Object-oriented Programming in Delphi in 2025?

Object-Oriented Programming (OOP) remains a core software development paradigm in 2025, and Delphi is a strong tool for leveraging its benefits. Delphi's support for classes, objects, inheritance, encapsulation, and polymorphism enables a structured and maintainable coding approach. OOP allows developers to model data as objects, enhancing code flexibility and efficiency. Encapsulation bundles data and methods, while inheritance facilitates code reuse via hierarchical class structures. Polymorphism allows objects to be treated as parent class instances, enabling versatile function processing. Delphi offers interface-based programming and reference counting to enhance its OOP capabilities. Future Delphi development will embrace cloud integration and cross-platform support, aligning with modern practices. Several books can help developers learn more, like one about the Delphi Murders or one about the history of Delphi. Resources are available for string array merging, JSON minification, and debugging techniques in Delphi. Mastering Delphi's object-oriented features is key for creating scalable and efficient applications.
