JavaBeans are reusable software components for Java that can be manipulated visually in a builder tool. Practically, they are classes written in the Java programming language conforming to a particular convention. They are used to encapsulate many objects into a single object (the bean), so that they can be passed around as a single bean object instead of as multiple individual objects. A JavaBean is a Java Object that is serializable, has a nullary constructor, and allows access to properties using getter and setter methods.
In order to function as a JavaBean class, an object class must obey certain conventions about method naming, construction, and behavior. These conventions make it possible to have tools that can use, reuse, replace, and connect JavaBeans.
The required conventions are:
Because these requirements are largely expressed as conventions rather than by implementing interfaces, some developers view JavaBeans as Plain Old Java Objects that follow specific naming conventions.

William Nelson Joy (born November 8, 1954), commonly known as Bill Joy, is an American computer scientist. Joy co-founded Sun Microsystems in 1982 along with Vinod Khosla, Scott McNealy, Andy Bechtolsheim and Vaughan Pratt, and served as chief scientist at the company until 2003. He is widely known for having written the essay "Why the future doesn't need us", where he expresses deep concerns over the development of modern technologies. He has two children, Hayden and Maddie.
According to a Salon.com article, during the early 1980s DARPA had contracted the company Bolt, Beranek and Newman (BBN) to add TCP/IP to Berkeley UNIX. Joy had been instructed to plug BBN's stack into Berkeley Unix, but he refused to do so, as he had a low opinion of BBN's TCP/IP. So, Joy wrote his own high-performance TCP/IP stack. According to John Gage,
"BBN had a big contract to implement TCP/IP, but their stuff didn't work, and Joy's grad student stuff worked. So they had this big meeting and this grad student in a T-shirt shows up, and they said, 'How did you do this?' And Bill said, 'It's very simple — you read the protocol and write the code.'"
Rob Gurwitz, who was working at BBN at the time, disputes this version of events.
In 1986, Joy was awarded a Grace Murray Hopper Award by the ACM for his work on the Berkeley UNIX Operating System.
Joy was also a primary figure in the development of the SPARC microprocessors, the Java programming language, Jini / JavaSpaces and JXTA.
On September 9, 2003 Sun announced that Bill Joy was leaving the company and that he "is taking time to consider his next move and has no definite plans".

Created to imitate a buzzer into a microphone and then taking a 0.05 second clip and repeating it over and over with Java so it actually sounds like a buzzer.
