Interface (Java and Corel Paradox Cross Reference Guide)

By Mike Prestwood

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

 
OOP Details
 

More object oriented (OO) stuff.

Interface

[Other Languages] 

An element of coding where you define a common set of properties and methods for use with the design of two or more classes.

Both interfaces and abstract classes are types of abstraction. With interfaces, like abstract classes, you cannot provide any implementation. However, unlike abstract classes, interfaces are not based on inheritance. You can apply an Interface to any class in your class tree. In a real sense, interfaces are a technique for designing horizontally in a class hierarchy (as opposed to inheritance where you design vertically). Using interfaces in your class design allows your system to evolve without breaking existing code.

Java:  "Interfaces" Yes
Corel Paradox:  "Interfaces" Not Supported
