Component Programming with Java Beans
The visual interface allows inspection of and implementation of both individual beans and their linkage (events) . This visual construction of linkage allows one to form nontrivial programs with multiple communicating components
A Java Bean component can be a simple GUI component such as a Button or a complex program with many properties and methods such as a spreadsheet.
Apart from the event mechanism used for communication and linkage, ComponentWare (and JavaBeans in particular) “just” give a set of universal rules (needed for interoperability) for rather uncontroversial (albeit good) object-oriented and visual programming practices
- Properties can only be accessed by methods (which must have special names)
