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.

Que es un Applet??

Es otra manera de incluir código a ejecutar en los clientes que visualizan una página web. Se trata de pequeños programas hechos en Java, que se transfieren con las páginas web y que el navegador ejecuta en el espacio de la página.

Los applets de Java están programados en Java y precompilados, es por ello que la manera de trabajar de éstos varía un poco con respecto a los lenguajes de script como Javascript. Los applets son más difíciles de programar que los scripts en Javascript y requerirán unos conocimientos básicos o medios del lenguaje Java.

La principal ventaja de utilizar applets consiste en que son mucho menos dependientes del navegador que los scripts en Javascript, incluso independientes del sistema operativo del ordenador donde se ejecutan. Además, Java es más potente que Javascript, por lo que el número de aplicaciones de los applets podrá ser mayor.


Ciclo de vida.

Para seguir el ciclo de vida de un applet, supondremos que estamos ejecutando en nuestro navegador el applet básico HolaMundo, a través de la página HTML que lo carga y corre.

Lo primero que aparece son los mensajes "initializing... starting...", como resultado de la carga del applet en el navegador. Una vez cargado, lo que sucede es:

Se crea una instancia de la clase que controla al applet
El applet se inicializa a si mismo
Comienza la ejecución del applet

Cuando se abandona la página, por ejemplo, para ir a la siguiente, el applet detiene la ejecución. Cuando se regresa a la página que contiene el applet, se reanuda la ejecución.

Si se utiliza la opción del navegador de Reload, es decir, volver a cargar la página, el applet es descargado y vuelto a cargar. El applet libera todos los recursos que hubiese acaparado, detiene su ejecución y ejecuta su finalizador para realizar un proceso de limpieza final de sus trazas. Después de esto, el applet se descarga de la memoria y vuelve a cargarse volviendo a comenzar su inicialización.

Finalmente, cuando se concluye la ejecución del navegador, o de la aplicación que está visualizando el applet, se detiene la ejecución del applet y se libera toda la memoria y recursos ocupados por el applet antes de salir del navegador.
