Que es un applet?

Un applet es una aplicación Java que se encuentra en web. El applet presenta unas diferencias con las aplicaciones comunes de Java porque no tienen ningún main, y son clases que tienen el mismo nombre que el del archivo que las incluye, que amplían la clase Applet del paquete java.applet. de esta manera de podria crear una direccion electronica que contenga la aplicacion de un programa ya realizado de esta manera podriamos compartir dicha aplicacion.
Incluso para los applets existe la versión JApplet de swing, que se utiliza para introducir componentes Swing en lugar de componentes AWT. Un applet necesita un archivo html que lo invoque. Por ejemplo, PrimoApplet.java, el applet que queremos poner en marcha, lo redactamos y el compilador genera PrimoApplet.class. Para ponerlo en marcha necesitamos un archivo html que incluya el.
Por eso en clase utilizamos el archivo web original del programa Java y lo modificamos para ver como al programar algunas lineas simple podemos modificar dicha pagina dotandola de nuestro nombre y tambien de cualquier aplicacion que ahi coloquemos.
Recordemos que se corre la pagina web modificada con la aplicacion applet y no la hoja de codigo creada por nosotros en el entorno de programacion .
Esta es una herramienta muy importande y de gran utilidad para crear paginas inteligentes en la web que podria ser beneficiosa para nuestro propio uso o de manera global dependiendo de lo que se desee hacer o lo que se desee crear y mostrar en dichas paginas ya q estan dotadas de un programa original en lenguaje Java
Un applet no se puede ejecutar de manera independiente ya que su programa base esta en otra plataforma .
Pero tiene otra utilidad como ser multiplataforma, esto quiere decir que es compatible con plataformas virtuales como Windows, Linux, etc.
En cualquier programa que soporte Java un applet podria ser utilizado
