In computing based on the [[Java (programming language)|Java]] Platform, '''JavaBeans''' is a technology developed by Sun Microsystems and released in 1996, as part of [Java Development Kit|JDK] 1.1.

In computing based on the Java Platform, '''JavaBeans''' are classes that encapsulate many [[Object (computer science)|objects]] into a single object (the bean). They are [[Serialization|serializable]], have a [[nullary constructor|zero-argument constructor]], and allow access to properties using [[Mutator method|getter and setter methods]]. The name "Bean" was given to encompass this standard, which aims to create [[Code reuse|reusable]] [[Component-based software engineering|software components]] for [[Java (programming language)|Java]].

The 'beans' of JavaBeans are classes that encapsulate one or more [[Object (computer science)|objects]] into a single standardized object (the bean). This standardization allows the beans to be handled in a more generic fashion, allowing easier [[code reuse]] and [[Type introspection|introspection]]. This in turn allows the beans to be treated as [[Component-based software engineering|software components]], and to be manipulated visually by [[https://en.wikipedia.org/wiki/Integrated_development_environment|editors and IDEs]] without needing any initial configuration, or to know any internal implementation details.

It is a reusable software component written in Java that can be manipulated visually in an application builder tool.

As part of the standardization, all beans must be [[Serialization|serializable]], have a [[nullary constructor|zero-argument constructor]], and allow access to properties using [[Mutator method|getter and setter methods]].
