Definición
Un applet es un componente de software que corre en el contexto de otro programa, por ejemplo un navegador web. El applet debe correr en un contenedor, que lo proporciona un programa anfitrión, mediante un Plug-In, o en aplicaciones como teléfonos móviles que soportan el modelo de programación por applets.
A diferencia de un programa, un applet no puede correr de manera independiente, ofrece información gráfica y a veces interactúa con el usuario, típicamente carece de sesión y tiene privilegios de seguridad restringidos. Un applet normalmente lleva a cabo una función muy específica que carece de uso independiente.
Función
Un applet es un componente de una aplicación que se ejecuta en el contexto de otro programa, por ejemplo un navegador web. El applet debe ejecutarse en un contenedor, que lo proporciona un programa anfitrión, mediante un plugin, o en aplicaciones como teléfonos móviles que soportan el modelo de programación por applets.
A diferencia de un programa, un applet no puede ejecutarse de manera independiente, ofrece información gráfica y a veces interactúa con el usuario, típicamente carece de sesión y tiene privilegios de seguridad restringidos. Un applet normalmente lleva a cabo una función muy específica que carece de uso independiente. El término fue introducido en AppleScript en 1993.
Ejemplos comunes de applets son las Java applets y las animaciones Flash. Otro ejemplo es el Windows Media Player utilizado para desplegar archivos de video incrustados en los navegadores como el Internet Explorer. Otros plugins permiten mostrar modelos 3D que funcionan con una applet.

Características principales de la librería AWT, SWING
Abstract Windows Toolkit (AWT) es el original juego de herramientas
de Java. Sus principales ventajas son que viene con cada versión de la tecnología Java, incluyendo aplicaciones de Java en navegadores web antiguos, y es muy estable.
AWT es un conjunto de herramientas muy simples con pocos componentes
con administradores de diseño, y eventos. Esto se debe a que Sun Microsystems decidió utilizar un mínimo común denominador (LCD) para un enfoque AWT.

SWING
Swing de Java, también conocido como parte de la Java Foundation Classes (JFC), fue un intento de resolver la mayor parte de las deficiencias de AWT. En Swing, Sun creó un muy bien diseñado, flexible y potente conjunto de herramientas
. Desafortunadamente, esto significa que Swing necesita tiempo para aprender, y es a veces demasiado complejo para situaciones comunes.
Swing está construido sobre las partes de AWT. Todas las partes de Swing son también parte de AWT. Swing utiliza el modelo AWT de evento y clases de apoyo, tales como colores, imágenes y gráficos. Los componentes Swing, los administradores de diseño, y los acontecimientos se resumen a continuación.
