Object Oriented Quotes & Sayings

Design Patterns - Elements of Reusable Object-Oriented Software — Erich Gamma

The problem with object-oriented languages is they've got all this implicit environment that they carry around with them. You wanted a banana but what you got was a gorilla holding the banana and the entire jungle. — Joe Armstrong

The problem is that when many products are produced, the majority of time and effort go into the engineering phase and not into the design phase. Object-oriented — Matt Weisfeld

I invented the term 'Object-Oriented', and I can tell you I did not have C++ in mind. — Alan Kay

Object-oriented programming is an exceptionally bad idea which could only have originated in California. — Edsger Dijkstra

All knowledge is oriented toward some object and is influenced in its approach by the nature of the object with which it is pre-occupied. But the mode of approach to the object to be known is dependent upon the nature of the knower. — Karl Mannheim

Object-oriented programming aficionados think that everything is an object ... this [isn't] so. There are things that are objects. Things that have state and change their state are objects. And then there are things that are not objects. A binary search is not an object. It is an algorithm — Alexander Stepanov

Shipping first time code is like going into debt. A little debt speeds development so long as it is paid back promptly with a rewrite. The danger occurs when the debt is not repaid. Every minute spent on not-quite-right code counts as interest on that debt. Entire engineering organizations can be brought to a standstill under the debt load of an unconsolidated implementation, object-oriented or otherwise. — Ward Cunningham

I don't predict the demise of object-oriented programming, by the way. Though I don't think it has much to offer good programmers, except in certain specialized domains, it is irresistible to large organizations. Object-oriented programming offers a sustainable way to write spaghetti code. It lets you accrete programs as a series of patches. Large organizations always tend to develop software this way, and I expect this to be as true in a hundred years as it is today. — Paul Graham

Certainly not every good program is object-oriented, and not every object-oriented program is good. — Bjarne Stroustrup

The combination of threads, remote-procedure-call interfaces, and heavyweight object-oriented design is especially dangerous ... if you are ever invited onto a project that is supposed to feature all three, fleeing in terror might well be an appropriate reaction. — Eric S. Raymond

Every dependency is like a little dot of glue that causes your class to stick to the things it touches. — Sandi Metz

Microsoft SQL Server, Oracle, DB2, and PostgreSQL let you create user-defined types (UDTs). The simplest UDT is a standard or built-in data type (CHARACTER, INTEGER, and so on) with additional check and other constraints. You can define the data type marital_status, for example, as a single-character CHARACTER data type that allows only the values S, M, W, D, or NULL (for single, married, widowed, divorced, or unknown). More-complex UDTs are similar to classes in object-oriented programming languages such as Java or Python. You can define a UDT once and use it in multiple tables, rather than repeat its definition in each table in which it's used. Search your DBMS documentation for user-defined type. UDTs are created in standard SQL with the statement CREATE TYPE. — Chris Fehily

Code without tests is bad code. It doesn't matter how well written it is; it doesn't matter how pretty or object-oriented or well-encapsulated it is. With tests, we can change the behavior of our code quickly and verifiably. Without them, we really don't know if our code is getting better or worse. — Michael C. Feathers

I used to be enamored of object-oriented programming. I'm now finding myself leaning toward believing that it is a plot designed to destroy joy. — Eric Allman

Object-oriented programming had boldly promised "to model the world." Well, the world is a scary place where bad things happen for no apparent reason, and in this narrow sense I concede that OO does model the world. — Dave Fancher

PHP as an object oriented programming language should be judged by how well it does the job, not on a preconceived notion of what a scripting language should or shouldn't do. — Peter Lavin

For me, the concept of design is more than object-oriented; it encompasses the design of processes, systems and institutions as well. Increasingly, we need to think about designing the types of institutions we need to get things done in this rapidly accelerating world. — John Seely Brown

Object-oriented programming as it emerged in Simula 67 allows software structure to be based on real-world structures, and gives programmers a powerful way to simplify the design and construction of complex programs. — David Gelernter

The best way to do research is to make a radical assumption and then assume it's true. For me, I use the assumption that object oriented programming is the way to go. — Bill Joy

Possibly the only real object-oriented system in working order. (About Internet — Alan Kay

Another trick in software is to avoid rewriting the software by using a piece that's already been written, so called component approach which the latest term for this in the most advanced form is what's called Object Oriented Programming. — Bill Gates

Object-oriented programming offers a sustainable way to write spaghetti code. It lets you accrete programs as a series of patches. — Paul Graham

But while you can always write 'spaghetti code' in a procedural language, object-oriented languages used poorly can add meatballs to your spaghetti. — Andrew Hunt

Object-oriented design is the roman numerals of computing. — Rob Pike

Some people believe that mirror neurons are also central to our ability to empathize with others and may even account for the emergence of gestural communication and spoken language. What we do know is that certain neurons increase their firing rate when we perform object-oriented actions with our hands (grasping, manipulating) and communicative or ingestive actions with our mouths. These neurons also fire, albeit less rapidly, whenever we witness the same actions performed by other people. Research — Sam Harris

I was impressed by the scene in Apollo 13 where the astronauts request confirmation of their calculations and several people at Mission Control dive for their slide rules. For several months after that, my standard response to statements like "We must implement multi-processor object-oriented Java-based client-server technologies immediately!" was "You know, FORTRAN and slide rules put men on the moon and got them back safely multiple times."
Tended to shut them up, at least for a moment. — Matt Roberts

Object-oriented languages use the paradigm of classes. In simplest terms, a class includes both data and the functions to operate on that data. You can create an instance of a class, also called an object, which will have all the data members and functionality of its class. Because of this, you can think of a class as being like a template, with each object being a specific instance of a particular type of class. For example, suppose you have a very simple class called Person, which has three fields (a data member is called a field in Java) and one method (a function is called a method in Java). The following code illustrates creating a simple class. For example, the first thing inside the beginning brace ({) is a constructor, a special kind of method that creates an instance of a class and sets its fields with their initial values. — Suresh Basandra
