Class..Object (Corel Paradox and Java Cross Reference Guide)

By Mike Prestwood

Corel Paradox versus Java: A side by side comparison between Corel Paradox and Java.

OOP Basics

Some languages support object-based concepts such as Paradox, Access, and VB Classic. Other languages have OO extensions and fully support object orientation in a hybrid fashion (such as C++ and Dephi for Win32). Finally, some lanages such as C#, VB.Net, Prism, and Java are entirely written in OO. Meaning, every line of code written must occur within a class).

Class..Object

[Other Languages]

Languages Focus

In short, a class is a data type, and an object is an instance of a class type. A class has methods (routines), properties (member variables), and a constructor. The current values of the properties is the current state of the object. The UML is one of the diagraming disciplines that allows you to document the various changing states of a series of objects.

Corel Paradox: Not Supported

Java: class..new

Unlike languages such as C++ and Object Pascal, every line of code written in Java must occur within a class.

Syntax Example:

//Declare class.

public class Cyborg {

  //Fields.

  private String cyborgName;

  private int age;

  //Constructor.

  public Person() {

  cyborgName = "unknown";

  age = 0;

//Create object from class.

Cyborg p = new Cyborg();

p.getClass(); //From the Object base class.
