JavaBeans

on

Back to some Java basics...

One of the main concepts of any programming language including JAVA is re-usability. Javabeans, helps in achieving this.

Javabeans encapsulates many objects into one object which can be accessible from multiple places.

Javabeans have the following features;
  • A default/no-argument constructor.
  • Private properties. 
  • Public getters and setters.
  • Should implement java.io.serializable.
  • Javabeans are mutable.

Why does Javabeans have to implement java.io.serializable???
                 As it allows to save, store and restore the state of a Javabean that one is working on.

What is meant by 'Javabeans are Mutable'???
                 it can change the states and fields after the object is created.
