Page 3: Object Oriented Classes

Object-Orientated classes have all the good things like encapsulation, inheritance and polymorphism. Object-Oriented interfaces are used in Java API's such as JDBC.

They offer FAT interfaces to maximise performance and flexibility. A lot of methods are often exposed that accept heavy architectural objects, such as Database connections. These so called API interfaces are implementation specific and require a lot of hand coding.

Here is an example Object Oriented file handler implementation, called FileObject:

public class FileObject
{
    public setFile( File file ) {...}
    public File getFile() {...}
    public void setContent( String content ) {}
    public String getContent() {...}
}
