我一直在关注如何使用JavaFX创建Java Gui程序的在线教程。
这是我在使用教程后制作的程序之一。我决定在命令行中添加一个计数器,它会显示订单数量以及客户选择,虽然我能够解决这个问题但计数器功能看起来效率低下。
我觉得添加另一个类只是添加orderNumber变量是错误的。
有关于简化此代码的建议吗?
另外,我还可以在订单后输出orderNumber?
public class Main extends Application {
private class Order {
public int orderNumber = 0;
}
Stage window;
Button button;
public static void main(String[] args) {
launch(args);
}
@Override
public void start (Stage primaryStage) throws Exception {
Order Number = new Order();
window = primaryStage;
window.setTitle("Luke's Sandwich's");
//Check Box's
CheckBox box1 = new CheckBox("cheese");
CheckBox box2 = new CheckBox("Bacon");
CheckBox box3 = new CheckBox("Tuna");
CheckBox box4 = new CheckBox("Tomatoes");
box1.setSelected(true);
//button
button = new Button("Order Now");
button.setOnAction(e -> {
Number.orderNumber++;
System.out.println("order: " + Number.orderNumber);
handleOptions(box1,box2,box3,box4);
});
VBox layout = new VBox(10);
layout.setPadding(new Insets(20));
layout.getChildren().addAll(box1,box2,box3,box4,button);
Scene scene = new Scene(layout,300,250);
window.setScene(scene);
window.show();
}
//Handle checkbox options
public void handleOptions (CheckBox box1,CheckBox box2,CheckBox box3,CheckBox box4){
String message = "user order:\n";
if(box1.isSelected())
message += "cheese\n";
if(box2.isSelected())
message += "bacon\n";
if(box3.isSelected())
message += "tuna\n";
if(box4.isSelected())
message += "tomatoes\n";
System.out.println(message);
}
}
