Question

这些点是java Graphics2D库用来绘制高质量形状的立方曲线，例如从Inkscape获取的svg路径请帮助我如何将这些点放在数组中以便一次性读取它们，而不是单独替换每条曲线代码：

import java.awt.*;
import java.awt.event.*;
import java.awt.geom.*;
import java.util.*;
import javax.swing.*;

public class Dal extends Frame {

    public static void main(String[] a){
       (new Dal()).setVisible(true);
        GeneralPath g=new GeneralPath();
    }

    Dal(){
        super("Test");
        setSize(500, 500);
        addWindowListener(new WindowAdapter() {
            public void windowClosing(WindowEvent e) {
                System.exit(0);
            }
        });
    }

    @SuppressWarnings("unused")
    public void paint(Graphics g) {
         Graphics2D g2d = (Graphics2D) g;
         g2d.setRenderingHint(RenderingHints.KEY_ALPHA_INTERPOLATION, RenderingHints.VALUE_ALPHA_INTERPOLATION_QUALITY);
         g2d.setRenderingHint(RenderingHints.KEY_STROKE_CONTROL, RenderingHints.VALUE_STROKE_PURE);
         g2d.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);

         GeneralPath path=new GeneralPath();
         path.moveTo(457.61616,470.82943 );               
            /* */
         path.curveTo(458.41016,425.70843 ,427.74316,392.55343 ,403.93516,370.91243 );

         path.curveTo(316.63916,610.12643 ,278.88716,614.34043 ,242.18316,610.35243 );
         path.curveTo(232.12112,609.27843 ,228.38012,619.29143 ,238.47016,621.92243 );

         path.closePath();
         g2d.draw(path);
         g2d.fill(path);
    }       
}

我有这个建议，创建一个Bezier类（继承自抽象Shape），它包含所有三个坐标。然后，您可以构建Bezier对象的集合并从中创建图形你能解释一下如何根据上述程序以编程方式通过Java来实现吗？感谢

数组或集合
