Soy nuevo en Java y quisiera que me expliquen por favor por qué la variable usada en while no es reconocida:
Código HTML:
do
{
//Scene theScene = theWindow.getScene();
RadioButtonGroup directionType = new RadioButtonGroup();
BRadioButton up = new BRadioButton("Up", false, directionType);
BRadioButton down = new BRadioButton("Down", false, directionType);
BRadioButton left = new BRadioButton("Left", false, directionType);
BRadioButton right = new BRadioButton("Right", false, directionType);
GridContainer directional = new GridContainer(2, 2);
directional.setDefaultLayout(new LayoutInfo(LayoutInfo.WEST, LayoutInfo.NONE, new Insets(2, 2, 2, 2), null));
directional.add(up, 0, 0);
directional.add(down, 0, 1);
directional.add(left, 1, 0);
directional.add(right, 1, 1);
ValueField vertexValueField = new ValueField(45, ValueField.NONNEGATIVE);
ValueField radiusValueField = new ValueField(1.0, ValueField.NONNEGATIVE);
ValueField maxErrorValueField = new ValueField(0.05, ValueField.NONNEGATIVE);
ValueField directionValueField = new ValueField(0.0, ValueField.NONNEGATIVE);
ComponentsDialog dlg = new ComponentsDialog(theFrame, "TearDrop Tool" ,
new Widget [] { directional, directionValueField, vertexValueField, radiusValueField, maxErrorValueField },
new String [] { "Orientation about z-axis: ", "or specific rotation about z-axis (degrees): ", "Vertex angle (degrees): ", "Radius: ", "Max error: " } );
if (!dlg.clickedOk()) return;
double theta = vertexValueField.getValue() / 180 * Math.PI;
double radius = radiusValueField.getValue();
double maxError = maxErrorValueField.getValue();
double directionAngle = directionValueField.getValue() / 180 * Math.PI;
double errorAngle = Math.acos((radius - maxError) / radius); // inverse cosine
double[B] numberSides [/B]= Math.ceil(((2 * Math.PI) - 2 * (Math.PI / 2 - theta)) / errorAngle); // rounded up
if (numberSides <= 10)
new MessageDialog(theFrame, "Please decrease the value of the maximum error");
}
while ([B]numberSides [/B]< 10);
El compilador dice: cannot find symbol : variable numberSides
