Object based Technology

Since you are reading this book, it's assumed that you have programmed in at least one other language before, even if only for one semester in college. Going one step further, I bet the language you programmed in was either C++, Java, or Perl—with Java and C++ being object-oriented (OO). Java specifically is OO by virtue of having all created objects extending from core Java language classes.

For those of you unfamiliar with object-oriented programming (OOP), it is a concept that allows you to create reusable objects or classes in code. An object or class has associated with it various characteristics and functionality that define what kind of properties and states it can take on. Once these are created and defined, it is possible to create new instances—sometimes referred to as a "children"—that inherit the ability to have the same characteristics of their "parent" object.
