您好,在我的框架上绘制图像时出现错误。我不确定这里出了什么问题。
我在这里收到以下错误。
Java: 77: cannot find symbol
symbol: variable image
location: class DrawComponent
g.drawImage(image, 0, 0, null);
class DrawComponent extends JComponent {
    public void paintComponent(Graphics g) {
        Graphics2D g2 = (Graphics2D) g;
        // draw a circle with the same center
        double centerX = 250;
        double centerY = 180;
        double radius = 20;
        Ellipse2D circle = new Ellipse2D.Double();
        circle.setFrameFromCenter(centerX, centerY, centerX + radius, centerY + radius);
        g2.setPaint(Color.RED);
        g2.fill(circle);
        g2.draw(circle);
        String filename = "SydneyOperaHouse.jpeg";
        try{
            Image image = ImageIO.read(new File(filename));
        }catch(IOException ex){
            // Handle Exeption
        }
        g.drawImage(image, 0, 0, null);
    }
}
任何帮助都会很棒:)
