Mostrar Temas
Quiero hacer un panel mas vistoso.
el poblema es que aun no lo controlo bien la programacion se me escapan algunos detalles y me dan error.
Codigo segun lo tengo echo.
Código:
public class tema2 {
public static void main(String[] args) {
//ejercicio de concepto básicos
JOptionPane.showMessageDialog(null, "Descripción: Pedir los coeficientes de una ecuación se 2º grado, y muestre sus soluciones reales.\nsi no existen, debe indicarlo.");
/* lo tengo desabilitado porque no me funciona la frame que quiero se que cuando meta todo lo que quiero solo tiene que aparecer lo del comentario.
frame1 obj = new frame1 ();
obj.setVisible(true);
obj.setLocationRelativeTo(null);
*/
double a=Double.parseDouble(JOptionPane.showInputDialog(null, "Introduce el primer coeficiente:"));
double b=Double.parseDouble(JOptionPane.showInputDialog(null, "Introduce el segundo coeficiente:"));
double c=Double.parseDouble(JOptionPane.showInputDialog(null, "Introduce el tercero coeficiente:"));
double d = b * b - 4 * a * c ;
if (d<0){
JOptionPane.showMessageDialog(null, "No existe soluciones Reales");
}else{
double x1 = (-b+Math.sqrt(d))/(2*a);
double x2 = (-b-Math.sqrt(d))/(2*a);
JOptionPane.showMessageDialog(null, "Los resultados de x1 y x2 es:\n\nResultado x1= "+x1+"\nresultado x2= "+x2);
}
veamos la explicacion, quiero que en vez de salir ventanitas pidiendome los datos y despues que me de los mensajes de los resultados. quiero que en esta ventana me haga todo.
Código:
public class frame1 extends javax.swing.JFrame {

cuando meta los tres datos y de a comprovar
en el renglon soluciones reales me diga correcto o erroneo. y en las dos de abajo que me de los dos resultados.
alguien que me adapte el codigo o que me diga como se hace para aprender de una maldita vez. que el profesor que tengo en el curso a distancia no me hace caso.
