错误：找不到合适的添加方法（BufferedImage）

I would like to know about the error that I am getting. I am trying to set individual pixels on a jframe with the bufferedimage class, but for some reason when I try to add them to the frame, I get an error saying that no suitable method has been found.

我想知道我得到的错误。我试图用bufferedimage类在jframe上设置单个像素,但出于某种原因,当我尝试将它们添加到框架时,我得到一个错误,说没有找到合适的方法。

Here is my code and the error can someone please tell me how to add the bufferedimage to the frame please.

这是我的代码和错误可以有人请告诉我如何将bufferedimage添加到框架请。

import javax.swing.JFrame;
import java.awt.image.BufferedImage;

public class gui {

  public static void main(String[] args) {
    int width = 40;
    int height = 80;
    int[] data = new int [width * height];
    JFrame frame = new JFrame("gui");
    BufferedImage image = new BufferedImage(width, height, BufferedImage.TYPE_INT_RGB);
    image.setRGB(0, 0, width, height, data, 0, width);
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.add(image);
    frame.setSize(400, 400);
    frame.setLocationRelativeTo(null);
    frame.setVisible(true);
    }
}

Error:

#1

You can pass the BufferedImage to an ImageIcon and then pass the ImageIcon to a JLabel. Finally, add this JLabel, which contains nothing but your image, as you would any other JLabel.

您可以将BufferedImage传递给ImageIcon,然后将ImageIcon传递给JLabel。最后,添加此JLabel,它只包含您的图像,就像您使用任何其他JLabel一样。

#2

As already indicated by the error message JFrame#add is undefined for a non-component such as BufferedImage. You could do

正如错误消息JFrame所示,对于非组件(如BufferedImage),未定义add。你可以做到

frame.add(new JLabel(new ImageIcon(image)));
