JavaBeans

In computing based on the <a href="/facts/Java_/9ScgFyAL">Java</a> Platform, JavaBeans is a technology developed by <a href="/facts/Sun_Microsystems/VJ9EzEFd">Sun Microsystems</a> and released in 1996, as part of <a href="/facts/Java_Development_Kit/qL5cDos6">JDK</a> 1.1.
The 'beans' of JavaBeans are classes that encapsulate one or more <a href="/facts/Object_(computer_science)/eX99dtAw">objects</a> into a single standardized object (the bean). This standardization allows the beans to be handled in a more generic fashion, allowing easier <a href="/facts/Code_reuse/DVohfy6U">code reuse</a> and <a href="/facts/Type_introspection/c0tKqdYB">introspection</a>. This in turn allows the beans to be treated as <a href="/facts/Component-based_software_engineering/eW5wvSHC">software components</a>, and to be manipulated visually by <a href="/facts/Integrated_development_environment/jbEINSQf">editors and IDEs</a> without needing any initial configuration, or to know any internal implementation details.
As part of the standardization, all beans must be <a href="/facts/Serialization/T00auFvv">serializable</a>, have a <a href="/facts/Nullary_constructor/Yok4sanz">zero-argument constructor</a>, and allow access to properties using <a href="/facts/Mutator_method/sKfxYzFM">getter and setter methods</a>.
