What Is Perl Object Oriented Programming?

Perl object-oriented programming allows computer programmers to use the Perl programming language to create computer applications. Read on to find out more about how Perl object-oriented programming works and how you can learn to use it. Schools offering Computer Programming degrees can also be found in these popular choices.

Perl Object-Oriented Programming Overview

The Perl programming language is popular among programmers due to its capabilities in text manipulation and its fast development cycle. Perl object-oriented programmers use its features to design computer programs and applications. According to Peter Wainwright's book Pro Perl, Perl wasn't originally an object-oriented language, nor does it require object-oriented programming. As a result, not all Perl programmers are familiar with it. Because Perl doesn't endorse any specific model of object-oriented programming, professionals who use it often find it quite flexible.

How It Works

In Perl object-oriented programming, objects give programmers an easy way to package information with the task instruction. As a result, objects must contain data in their properties and perform actions using particular methods. For example, a programmer could use an object to create an address book application. The object would have properties used to keep a person's name, address and contact information on file. The object also would contain the methods that allowed a user to print a mailing label or alter a person's address.

Academic Options

Some colleges and universities offer courses in object-oriented programming as part of their computer science curriculum. There are also several free Perl object-oriented programming tutorials available online. Those who want to use Perl object-oriented programming must learn to perform multiple tasks, including these:

  • Creating objects using constructors
  • Calling classes to use objects
  • Writing object classes
  • Determining inherited characteristics of objects
  • Redefining and extending object behaviors
  • Implementing debugging strategies
  • Keeping data private
