試圖將圖像繪製到JPanel

對不起，我知道這個主題有很多信息，但我仍然卡住了。我有兩個面板mainPanel和sidePanel。我想要做的是將一個圖像繪製到sidePanel。我的sidePanel將有其他組件，如按鈕和標籤。我可以使用JLabel將圖像添加到sidePanel，但是，圖像的大小和位置是一個問題。因此，我正在嘗試使用Graphics g將圖像繪製到sidePanel上。如果任何人可以幫助很多將不勝感激。謝謝你所有的幫助.` import java.awt.BorderLayout;試圖將圖像繪製到JPanel

public class ImagePanel extends JPanel { 

    private BufferedImage image; 

    public ImagePanel() { 
     try {     
      image = ImageIO.read(new File("image name and path")); 
     } catch (IOException ex) { 
      // handle exception... 
     } 
    } 

    @Override 
    protected void paintComponent(Graphics g) { 
     super.paintComponent(g); 
     g.drawImage(image, 0, 0, null); // see javadoc for more info on the parameters    
    }
