Basic Java Concepts

Java beans conform to a Java class with some kind of rule

private int size;public int getSize() { return size; }

Let the user start with GetSize, so that when the GetSize implementation is modified one day, it does not break backwards compatibility. This public int getsize () {return size;} Is the Java Bean.

Java Bean Features:

1. All properties are private
2. Provide default construction method
3. Provide getter and setter
4. Implement Serializable interface
