Sample Questions

Suggested answer:

One type of object-oriented technology is an object-oriented programming language. An object-oriented programming language is a programming language used to develop object-oriented systems. For example, just as English, French, and Italian are different languages you can use to write a paper, java and C++ are two different languages you can use to write a program. An object oriented programming language must be used in order to develop an object-oriented system.

A second type of object-oriented technology is an object-oriented database system. Object-oriented databases work with traditional database information and also with complex data types such as diagrams, schematic drawings, video, sound and text documents.

3.1.1 Single Inheritance

3.1.2 Multiple Inheritance

3.1.3 Aggregation

3.2 What is Typing?

3.2.1 Issues when using strong typing

Solving these issues

3.2.2 Benefits of using strong typed languages

There are a number of important benefits to be derived from using strongly typed languages:

Without type checking, a program in most languages can ‘crash’ in mysterious ways at runtime.

In most systems, the edit-compile-debug cycle is so tedious that early error detection is indispensable.

Type declarations help to document programs.

Most compilers can generate more efficient object code if types are declared.
