Java Beans :
1. public , java.io.Serializable
2.
3. Properties getter & setter method
[ ]Java Beans & Enterprise Java Bean [JAVA]
• Have a public default (no argument) constructor
• allows access to properties using accessor (getter & setter) methods
• Implement java.io.Serializable](https://image.slidesharecdn.com/springframework-151110053600-lva1-app6892/85/Spring-framework-137-320.jpg)

- 133. Framework Library Library vs. Framework
- 134. Library vs. Framework A library is just a collection of class definitions. The reason behind is simply code reuse. Library
- 135. Library vs. Framework • In framework, all the control flow is already there. • There's a bunch of predefined white spots that you should fill out with your code. • Your code will be called by the framework when appropriately. • Developers do not need to worry about if a design is good or not, but just about implementing domain specific functions.
