Last Update: November 17, Email Address. And what about that forum topic where someone asked about Objective-C? Are these all different versions of the same thing? Or are they not even related at all? C came first, and the rest were either built off of C or inspired by it. While some types of programming languages function by providing computers with a list of tasks to execute, object-oriented programming languages allow programmers to create virtual objects within their code—each with unique attributes and abilities—that can then interact with one another to perform actions.

A simple way to picture it is to think of object-oriented programming as a virtual set of building blocks. Each block is an object that is defined by a specific shape, size, etc. Can certain blocks be stacked on top of it?

Where is it placed right now? Groups of objects can then be given instructions, for instance a group of A blocks can be used to build a tower, while a group of B blocks can be instructed to create steps leading to the top of the tower.

The benefit of this object model is that it reduces complexity by mimicking real world building and giving programmers a clear structure to work with. Sign Out View Profile.

Over here, we will compare the two programming languages based on some key parameters: Ease of learning — Although this differs from person to person, app developers have a tendency to try to learn Objective C first.

This probably has a bit to do with the better revenues that iPhone apps have the potential to earn, in comparison to Android applications. While in Java, core data and proxy objects have to be handled by ciders, Objective-C allows developers to implement a much simpler " message passing " method. All that is required is passing the text string to the corresponding object. Extent of manual coding required — Java would edge this round, since even dedicated iPhone app development experts agree that programming in Objective-C requires significantly more manual typing.

What is often overlooked is the fact that method names in the Cocoa framework are, by default, longer. Hence, it is not a fault of the language per se; in any case, new, shorter methods can be declared. For that, coders have to be really proficient in handling function pointers though.

Creation of instance variables — All instance variables attributes from class instances in Objective-C have to be defined in a. In Java, however, instance variables cannot be accessed or initialized via classes.

In addition, attributes in Objective-C are protected, unless something is defined as "s pecial. Since Java codes have to be compiled, as well as interpreted, the performance speeds tend to be lower. However, in terms of general acceptance among new programmers, this is not much of an issue.
