TRABAJO FINAL

• Características principales de una librería AWT y SWING.

AWT significa Abstract Window Toolkit. Permite hacer interfaces gráficas mediante artefactos de interacción con el usuario, como botones, menús, texto, botones para selección, barras de deslizamiento, ventanas de diálogo, selectores de archivos, etc. Y por supuesto despliegue gráfico general.
Un widget es un elemento gráfico con el que el usuario puede interactuar.
Ocupa una porción rectangular en una ventana.
Existen diversos tipos: botones, áreas de texto, etiquetas, etc.
El kit AWT implementa los widgets más usuales. Para usarlos es necesario importar las clases del paquete java.awt:

SWING
Swing es una biblioteca gráfica para Java. Incluye widgets para interfaz gráfica de usuario tales como cajas de texto, botones, desplegables y tablas.

Ventajas
* El diseño en Java puro posee menos limitaciones de plataforma.
* El desarrollo de componentes Swing es más activo.
* Los componentes de Swing soportan más características.


• Defina un APPLET, describa su funcionamiento.

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


• Realizar un applet para operaciones con matrices que presente la siguiente estructura.
