Key to Object-Oriented Programming (KOP) is a method that provides developers with a way to create reusable components and reusable modules within an application. It is a way to maintain backwards compatibility between code and classes. A common misconception among many programmers is that they should create “stand-alone” objects in the application that can be reused throughout multiple applications. However, this is just one of the many advantages associated with object oriented programming (OOP). This article highlights some of the benefits of OOP:

Key to Object-Oriented Programming

With KOP, a developer does not need to maintain any external interfaces for the component or module. An object oriented developer should be able to swap an interface for a class or use a single class as an interface for the program. The flexibility provided by an object-oriented program allows a programmer to create reusable components by reusing classes, interfaces, and other objects. This results in an increase in the productivity of the programmer as well as an increase in the code’s readability.


Another advantage of using an object oriented programming paradigm is the use of inheritance. An object oriented developer uses classes, instead of interfaces, to provide code reuse and code modification. By simply renaming an interface, or redefining an existing class, a programmer is provided with a means to modify and extend the logic of their program. Furthermore, object-oriented code can be more modular. Classes and interfaces can be combined into reusable modules that can be used in a variety of future applications.

A key benefit of using an object oriented language is the use of a virtual machine. In this scenario, a programmer creates an executable file or software that runs on the computer via a VGA card, serial port, or USB port. The virtual machine interprets the source code generated by the developer and compiles the resulting code into machine code. Once compiled, the resulting executable file is then loaded onto the operating system.


Since an object oriented programming environment is written in Java, a Java application can be run on a wide variety of computers without the developer needing to concern themselves with many of the concerns of the computer hardware. Java also supports a large number of libraries. These libraries allow the Java developer to leverage the power of other high-level languages. Additionally, most Java applications are self-contained, requiring little or no additional code from the developer.

While object-oriented software development can be time consuming for some developers, the cost of object-oriented software is considerably lower than traditional methodologies. This is because an object oriented software environment is made up of many small parts instead of a single large module. Also, the output is typically much cleaner and faster because it is written directly to the computer’s hard drive, rather than stored in a file.


Object oriented software development is based on the idea that the source code should be self-contained, meaning that all sources of the program are available for reference by other parts of the program. This allows the Java programmer to make changes to the program without worrying about writing separate code for each change. The result is a much smaller total size of the executable program. This results in a faster execution speed and reduced memory usage. It also results in fewer crashes, as a result of code being less likely to be affected by errors and problems within the Java virtual machine itself.

Java also provides support for object-oriented software development. This is achieved through the use of Java interfaces, which provide methods and features that would otherwise be provided by Java classes. For instance, XML is the commonly used XML syntax. Classes in Java also provide support for entity management and other related entity-oriented programming concepts. Java also makes it easy to create lightweight components through the use of Java components.
