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 opciones de grupo)Java Application / luego en NextProject Name: nombre New / JFrame FormClass name, le ponen un nombre.Variable Name/ *poner: txtingresesueldo */Name/* poner: txtbonificacion */Change Variable Name/* poner: txtdescuento* /Change Variable Name/ *poner: txtresibir* /Change Variable Name/* poner: txt1 *// Edit text/ poner: Ingrese Sueldo;/ Edit text/ poner: Seleccione Bonificacin;/ Edit text/ poner: Seleccione Bonificacin (descuento);/ Edit text/ poner: 8 %;/ Edit text/ poner: 10 %;Edit text/ poner: s/.150.00;/ Edit text/ poner: 11 %;/ Edit text/ poner: 13%;/ Edit text/ poner: Total con Bonificacin:/ Edit text/ poner: Total de Descuento:/ Edit text/ poner:Total Neto a Recibir:/ Edit text/ poner: SNP (Sistema Nacional de Pensiones)Change Variable Name/ poner: radio1// Edit text/ poner: AFP (Administracin de Fondo de pensiones)/ Change Variable Name/ poner: radio2 // Edit text/ poner: Familiar:/ Change Variable Name/ poner: check1 // Edit text/ poner: Productividad:/ Change Variable Name/ poner: check2 // Edit text/ poner: Escolaridad:/ Change Variable Name/ poner: check3/ Edit text/ poner: Calcular/ Change Variable Name/ poner: botoncalcular /double sueldo1=0;double sueldo2=0;int cuenta=0;double n1=0;double total=0;double descuento=0;n1=Double.parseDouble(txtingresesueldo.getText());sueldo1=((n1*8)/100)+n1;sueldo2=((n1*10)/100)+n1;if (check1.isSelected());{cuenta++;total+=((n1*8)/100));}if (check2.isSelected());{Cuenta++;}total+=((n1*10)/100);}if (check3.isSelected());{Cuenta++;}total+=150;{if (radio1.isSelected());}descuento=0.11*(total+n1);{if (radio2.isSelected());}descuento=0.13*(total+n1);{txtbonificacion.setText(String.valueOf(total+n1));txtdescuento.setText(String.valueOf(descuento));txtrecibir.setText(String.valueOf((total+n1)-descuento));txt1.setText(String.valueOf(cuenta));txtingresesueldo.setText();txtbonificacion.setText();txtdescuento.setText();txtrecibir.setText( );txt1.setText( );txtingresesueldo.grabFocus();
