Interfaces de usuario con Netbeans
Practica de Laboratorio
Para diseñar interfaces gráficas (Ventanas con componentes(etiquetas, cajas de texto, botones, barras de desplazamiento,etc))
Java nos proporcionado algo muy interesante, que es una biblioteca de clases denominada JFC(Java Foundation Classes =clases base de java). Actualmente allí se encuentra las siguientes API: Swing, AWT, Accesibilidad, Java 2D y soporte para arrastrar y colocar.
Swing: Proporciona componentes escritos en Java para diseñar lo antes mencionado, ejecutandose uniformemente en cualquier plataforma nativa que soporta la maquina virtual de java (JVM)
AWT(Abstract Windows Toolkit=kit de herramientas de ventanas abstractas): Proporciona un conjunto de componentes para diseñar interfaces gráficas de usuario comun a todas las plataformas nativas.
Pero a la hora de programar cual usamos??? La diferencia entre estos es que los componentes Swing estan implementados absolutamente con codigo no nativo lo que los hace independientes de la plataforma, razon que justifica totalmente su uso. Ademas proporcionan mas capacidades que los componentes AWT.
Los componentes Swing son facilmente reconocibles porque comienzan el nombre con la letra J.
Por ejemplo el componente AWT Button tiene su equivalente en Swing al JButton.
Los componentes AWT se localizan en el paquete java.awt y los Swing en el paquete javax.swing.
Todo Componente Swing es subclase de la clase Jcomponent.

04.03 Ciclos Infinitos
Ciclo
infinito
Cuando en un
ciclo la condición siempre es verdadera se dice que es un ciclo infinito, pues
nunca saldrá del ciclo y el programa no
termina. Para
evitarlos hay que estar seguros que en el bloque de estatutos haya un estatuto
que modifique el valor de la
condición de
tal modo que llegue a ser falsa.
Ejemplos de
ciclos infinitosEjemplo I
En este ejemplo supongamos que en el applet de las
inversiones, nos equivocamos en la condición del while y en lugar de tener
(saldo < invfinal), tuviéramos (invinicial < invfinal), en este caso, la
condición siempre hubiera sido verdadera, pues a quien le estamos acumulando es
a la variable saldo, no a invinicial. Este es un error de ejecución difícil de
encontrar.
Ejemplo II
En este ejemplo
supongamos que en el applet de los dígitos, donde usamos el do while, en la
condición del while no tenemos (x > 0) sino que utilizamos por error la
variable cant, teniendo while (cant > 0) en lugar de while (x > 0),
obviamente esto siempre seria verdad, ya que cant siempre se está
incrementando. A su vez este error es difícil de ver.
El applet
seguirá ejecutándose (por siempre) y no nos daremos cuenta, es importante
observar que el botón sigue seleccionado, lo cual indica que el applet esta
procesando las instrucciónes puestas en el actionPerformed, como se observa en
la siguiente figura:
Nunca pondrá
nada en el segundo campo de texto y habrá que cancelarlo.
Apertura del Debate
en el grupo de Facebook, escoger una pregunta y exponer la explicación al
utilizar los siguientes comandos con un Ejemplo.
