UNIVERSIDAD PRIVADA TELESUP

CASO PROPUESTO 1Se necesita una aplicacin informtica que calcule el total a facturar por la compra de los siguientes productos (debe representarse con casillas de verificacin):

ProductoCosto (US $)

CASE32.00

Microprocesador75

Memoria 48

Mainboard70

Disco Duro120

Monitor130

Teclado5

Mouse5

Lector de CD ROM12

Adicionalmente que tipo de descuento se har efectivo, existen las siguientes posibilidades: 0%, 5%, 8% (Deben representarse con radiobuttons)Calcular el costo total de los productos y el descuento pertinente.

Crear el diseo de formulario de acuerdo a su criterio, utilice controles checkbox (casillas de verificacin) y radiobuttons (botones de opcin de grupo).

CASO PROPUESTO 2

Crear una aplicacin Java que resuelva el siguiente caso prctico:

Se necesita una aplicacin informtica que ayude a calcular los haberes mensuales de los trabajadores de una empresa, para lo cual se le pide a Ud. que desarrolle el siguiente programa:

Luego de ingresar el monto de sueldo bsico mensual, se debe seleccionar con casillas de verificacin, las bonificaciones a las cuales el trabajador est afecto (pueden ser una, varias o ninguna).Tipo de BonificacinPorcentaje de Bonificacin con relacin al sueldo bsico

Familiar8%

Productividad10%

EscolaridadS/. 150.00

Adicionalmente sealar el sistema de pensiones al cual est afiliado el trabajador (slo se puede escoger una de cualquiera de las dos opciones)

Tipo de Sistema de Administracin de PensionesPorcentaje de Descuento con relacin al sueldo bsico

SNP (Sistema Nacional de Pensiones)11%

AFP (Administracin de Fondo de Pensiones)13%

Luego de seleccionar las bonificaciones y el tipo de sistema de administracin de pensiones hacer click en el botn calcular, para hallar: el monto total de la bonificacin, el monto total de descuento y el neto a percibir.

Crear el diseo de formulario de acuerdo a su criterio y lo enseado en la ltima clase, utilice controles checkbox (casillas de verificacin) y radiobuttons (botones de opcin de grupo).
