Foil 4 What are JavaBeans?

From Javabeans Basic Information Track Computational Science Course CPS616 -- Spring Semester 1999. by Geoffrey Fox, Nancy McCracken, Wojtek Furmanski


"Reusable software components that can be manipulated visually in a builder tool."
They are Java's implementation of "component-based" visual programming
This modern software engineering technique produces a new approach to libraries which become a "software component infrastructure(SCI)"
There is a visual interface to discovery of and setting of values of and information about parameters used in a particular software component
JavaBeans uses the event model of JDK1.1 to communicate between components
  • This is exactly same as new AWT event model and shows power of this model
