Object-Oriented Programming Languages

The following programming languages are some of the most commonly used object-oriented languages.  They are all similar in some ways and different in others.  Some are derived from the C language, some from Pascal.  Some incorporate Smalltalk, others do not.  Some are multi-paradigm languages.  Each language is different and has its advantages and disadvantages.  The program you are writing and its needs determine which language would best facilitate it.

JAVA

Java derives most of its syntax from C programming language.  Although it shares syntax with C it has a simpler object model and fewer low-level facilities.  Java uses a compiler to transfer Java programming language into Java bytecode, which can be interpreted by any Java Virtual Machine.  This enables Java programming language to be read by any computer regardless of the computer’s architecture.  The Java Virtual Machine acts as an interpreter for your computer and translates the bytecode into machine code readable by your computer.  This enables Java programming to be written once and run anywhere.  Due to its ability to be ran on any computer Java is currently one of the most popular programming languages.  It is used for application software and web applications.

C++

One of the most popular programming languages ever created is the C++ language.  C++ was derived from C with classes added to it.  C++ has many uses including: writing systems software, application software, device drivers, embedded software, high-performance server and client applications, hardware design synthesis, and video game software. 

Python

Python is a multi-paradigm programming language.  It permits the use of object-oriented programming, structured programming, functional programming, aspect-oriented programming, and many other paradigms with the use of extensions.  Languages such as C, C++, and Java are incorporated into Python.  Python is a scripting language that emphasizes code readability, simplicity, and ease of use.  Although C and C based languages are incorporated in Python, Python’s primary language abandons the C language for more readable commands.  Python utilizes dynamic typing and automatic memory management.  Python is a scripting language for web applications that is used by many large organizations including YouTube, Google, Yahoo!, CERN, and NASA.  It also is used for 3D animation packages and 2D imaging programs.

Objective-C

Objective-C is an object oriented programming language used primarily for Macintosh’s OS X and iOS operating systems.  Objective-C is a reflective language meaning that it can observe and modify its own structure and behavior in runtime.  Objective-C adds a Smalltalk style of messaging to the C programming language. Objective-C defers some decisions until runtime that C++ would make at compile time.  These decisions are known as dynamic dispatch, dynamic typing, and dynamic loading.

Delphi

Delphi is an object oriented, visual programming environment.  It is used to develop 32-bit and Microsoft.net applications that can be used on Windows and Linux operating systems as well as on the Internet.  Delphi has many different revisions, most currently Embarcadero Delphi XE, and is still evolving to complement evolving computer technologies.  Delphi allows you to build applications faster with pre-built components and a drag and drop visual design.  Many applications are written in Delphi including Skype and FL Studio (formerly Fruity Loops).

Ruby

Ruby is a general purpose, multi-paradigm, programming language that supports object-oriented, dynamic, functional, imperative, and reflective paradigms.  It utilizes syntax inspired by the Perl programming language with Smalltalk like features.  Ruby also uses a dynamic type system and automatic memory management like Python’s programming language.  Ruby is mainly used to create interactive web pages.
