FAQ's
A portable, cross-platform model created in the Java programming language is known as JavaBeans. Its constituent parts are known as beans. JavaBeans, to put it simply, are classes that combine many objects into a single object. It facilitates access to these items from various locations.
There are no conditions or arguments in the default function Object() { [native code] } that JavaBeans offer. JavaBeans can implement the Serializable interface and are capable of becoming serializable. Most JavaBeans feature a number of "getter" and "setter" methods.
Java Bean is not handled by Spring IOC, but Spring Bean is. While Spring Bean doesn't necessarily need to be serializable, Java Bean always is. While Spring Bean does not require a default no-arg function Object() { [native code] }, Java Bean must.
Most of them are still in use, yes. But they apply mostly when you are designing an application.
Serialization is the process that makes persistence feasible. Object serialization is the process of transforming an item into a data stream and then storing it. Then, by deserialization, any applet, program, or tool that makes use of that bean can "reconstitute" it. The item is then put back to how it was originally.
