Eclipse：插入＆＃39;}＆＃39;完成阻止

Question

我有以下代码来绘制一个工作正常的矩形：

public void paintComponent(Graphics g) {
        super.paintComponent(g);
        Graphics2D g2 = (Graphics2D) g;
        g2.setStroke(new BasicStroke(10));
        g2.setPaint(new Color(128, 0, 0));
        Rectangle2D.Double s = new Rectangle2D.Double(20.0, 20.0, 100.0, 50.0);
        g2.draw(s);
    }

用我的代码替换后

public void paintComponent(Graphics g) {
        super.paintComponent(g);
        Graphics2D g2 = (Graphics2D) g;
        g2.setStroke(new BasicStroke(10));
        g2.setPaint(new Color(128, 0, 0));
        Shape[] shapeList = new Shape[3];    
        shapeList[0] = new Rectangle2D.Double(20.0,20.0,40.0,70.0);  
        shapeList[1] = new Ellipse2D.Double(20.0,20.0,40.0,70.0);  
        int[] x = { 10, 50, 70 };  
        int[] y = { 20, 70, 20 };  
        shapeList[2] = new Polygon(x,y,3);  
         // now update the display 
        for (int i=0; i<4; i++){
            g2.draw(shapeList[i]);
            }
          
    }

我收到语法错误，告诉我必须插入＆＃34;}＆＃34;在这一行

g2.draw(shapeList[i]);

我还没弄明白为什么，但我想我在某处遗漏了什么。

这是我的全部代码：

import java.awt.*;
import java.awt.geom.Ellipse2D;
import java.awt.geom.Rectangle2D;

import javax.swing.*;

public class FrameDrawings extends JPanel {
    public FrameDrawings() {
        setBackground(Color.white);
    }

    public void paintComponent(Graphics g) {
        super.paintComponent(g);
        Graphics2D g2 = (Graphics2D) g;
        g2.setStroke(new BasicStroke(10));
        g2.setPaint(new Color(128, 0, 0));
        Rectangle2D.Double s = new Rectangle2D.Double(20.0, 20.0, 100.0, 50.0);
            Shape[] shapeList = new Shape[3];    
            shapeList[0] = new Rectangle2D.Double(20.0,20.0,40.0,70.0);  
            shapeList[1] = new Ellipse2D.Double(20.0,20.0,40.0,70.0);  
            int[] x = { 10, 50, 70 };  
            int[] y = { 20, 70, 20 };  
            shapeList[2] = new Polygon(x,y,3);  
             // now update the display 
            for (int i=0; i<4; i++){
                g2.draw(shapeList[i]);
                }
              

    }
}
