Estoy haciendo una calculadora con el JBuilder. Mi problema es que me realiza todas las operaciones menos la divisi贸n. He cambiado el tipo de variable de enteras(int) a real (float), pero cuando hago esto solo me deja realizar un calculo y se bloquea. Hay alguna forma de recoger los n煤meros de la pantalla y transformarlos en float sin que se bloquee.

Por el codigo que has puesto creo que el fallo es que te has dejado un punto y coma.Pon algo de codigo por que si no no sabemos que es lo que has hecho :-).
Un saludo

Gracias Enrique, me has salvado la vida con el c贸digo de tu calculadora estaba en un apuro por un examen de programaci贸n y te comento que el requisito de entrada al examen era de entregar el c贸digo fuente de un calculadora. Te consulto a ver si puedes ayudarme a crear un ejecutable de esta calculadora.
Gracias Nuevamente, saludos

puedes hacer algo asi
num2=Float.parseFloat(TxtVisor.getText());resu=num1/num2;
TxtVisor.setText(Float.toString(resu));break;
