将 UML 图转换为代码

Question

我在将此 UML 图设置转换为代码时遇到问题。我知道 Class 是顶部，后面是变量和方法。我是 Java 的新手，这可能是我遇到过的最令人困惑的事情。我不是 100% 确定如何为此创建 "model" 或主要代码部分，但这是我目前为域 class 使用的代码 started/attempted。我在正确的轨道上吗？还是我完全迷路了。任何提示，或向我发送正确方向的东西将不胜感激。

  //This is the main .java file
  public class Assignment3 extends Application {



@Override
public void start(Stage stage) throws Exception {
    Group root = new Group();
    Scene scene = new Scene(root);
    Canvas canvas = new Canvas(400, 300); // Set canvas Size in Pixels
    stage.setTitle("FXGraphicsTemplate"); // Set window title
    root.getChildren().add(canvas);
    stage.setScene(scene);
    GraphicsContext gc = canvas.getGraphicsContext2D();

    Castle stateDomain = new Castle();
    Castle drawDomain = new Castle();

    stage.show();
    }


 public static void main (String[] args) {
     launch ( args );
 }

 // .class file that is utterly awful and I don't know where to go

 public class Castle {


 private String castleName;
 private double castleSize;
 private double castleX;
 private double castleY;
 private int domainX;
 private int domainY;
 private String castleColor;
 private String domainName;



public void stateDomain ( String castleName, int domainX, int domainY, String castleColor ) {
    this.castleName = castleName;
    this.domainX = domainX;
    this.domainY = domainY;
    this.castleColor = castleColor;    
}

public void drawDomain ( GraphicsContext gc ) {



}

我想指出我只是在寻找方向。此时的任何事情都会非常有用，无论是 link 到另一个 post 还是让我的大脑运转的一小段代码。谢谢。

描述类之间静态关系的最抽象方法是使用关联 link，它简单地说明两个 link 之间存在某种 link 或依赖关系类或更多。有弱协会和强协会。对于你的情况，我认为它是强关联。

public class Domain 
{
    private double x, y, size;
    private String name;

    public void state(String name, int x, int y, Color color) {
            //TODO
    }

    public void draw(arguments) {
        //TODO
    }
}


public class Castle
    {
        //all arguments in diagram and now you need a reference to the class Domain

        private Domain domain;

        //The rest is just writing what is in the diagram

    }

但我必须说你的图表非常不完整。请看一下：https://en.wikipedia.org/wiki/Class_diagram
