TRABAJO- PREGUNTA2
¿Qué es un Applet?
• Definición: Podemos decir que un applet es un componente de unaaplicación 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 porapplets.
Un applet no puede ejecutarse de manera independiente. Un appletnormalmente lleva a cabo una función muy específica que carece de uso independiente.
• Funcionamiento
Un Java applet es un código JAVA que carece de un método main, por eso se utiliza principalmente para el trabajo de páginas web, ya que es un pequeño programa que es utilizado en una página HTML y representado por una pequeña pantalla gráfica dentro de ésta.
Un applet Java es un applet escrito en el lenguaje de programación Java. Los applets de Java pueden correr en un navegador web utilizando la Java Virtual Machine (JVM), o en el AppletViewer de Sun.
Java puede funcionar como una aplicación sola o como un "applet", que es un pequeño programa hecho en Java. Los applets de Java se pueden "pegar" a una página de Web (HTML), y con esto puedes tener un programa que cualquier persona que tenga un browser compatible podrá usar.
Java funciona de la siguiente manera: El compilador de Java deja el programa en un Pseudo-código (no es código maquinal) y luego el intérprete de Java ejecuta el programa (lo que se conoce como el "Java Virtual Machine"). Por eso Java es multiplataforma, existe un intérprete para cada máquina diferente.
Para entender bien como funciona un applet de Java vean el siguiente ejemplo:
1. Existe un código de Java en un servidor de Web. (Los códigos de Java se caracterizan por tener la extensión *.class).
2. Si el usuario realiza otra conexión a otro URL o se sale del browser, el programa se deja de ejecutar y en la computadora no queda rastro de el.Una persona en Internet, con un browser compatible con Java, realiza una conección al servidor.
3. El servidor envía el documento HTML y el código en Java (*.class).
4. En la computadora del usuario remoto llegan ambos, y la Máquina Virtual de Java, que está en el browser, transforma el código Java en un código que entienda la máquina local y se ejecuta el programa dentro de la página de Web.
5. Una persona en Internet, con un browser compatible con Java, realiza una conección al servidor.

Librería AWT
Se trata de una biblioteca de clases Java para el desarrollo de Interfaces de usuario Gráficas las cuales permiten generar componentes gráficos y gestionar eventos.Su aspecto visual depende de la plataforma.
Caracteristicas:
1. Genera interfaces gráficas, independiente de la plataforma en que se ejecute la aplicación.
2. Los Contenedores contienen a los controles básicos
3. Depende de la máquina en que se ejecuta la aplicación
4. No tiene formato de recursos sin poder separar el código de la interface.
5. No se usan posiciones fijas están situados a través de una disposición controlada (layouts)
6. Alto nivel de abstracción al entorno de ventanas en que se ejecute la aplicación
7. La arquitectura de la aplicación depende del entorno de ventanas, no tiene un tamaño fijo
Estructura
Container: Contenedor.
Label: Etiqueta de texto
Button: Botón de comando
Canvas: Area de dibujo.
Choice: Lista de selección.
List: Lista de datos.
Scrollbar: Barra de desplazamiento.
TextComponent: Componente de texto.

Librería Swing
Proporciona componentes de presentación visual independiente a la plataforma en la que se ejecuta. Swing extiende AWT y añade nuevas características, mejoras y componentes para interactuar con el usuario, tales como árboles, pestañas, tablas, etc.
Existen muchas versiones de swing en el mercado
Caracteristicas
1.Cambia la gestión del texto creando texto de colores con distintos tipos de caracteres.
2. Se puede introducir imágenes y decodificar los archivos de html, rtf.
3. Gestionar sucesos con el paquete de java.awt.event.
