import javax.swing.*;
import java.awt.*;
public class PrintDemo{
public static void main(String[] args){
PaintFrame frm = new PaintFrame();
frm.setVisible(true);
}
}
class PaintFrame extends JFrame{
PaintFrame(){
setBounds(200,300,540,450);
PaintPanel p = new PaintPanel();
add(p);
}
class PaintPanel extends JPanel{
public void paintComponet(Graphics g){
Image image = new ImageIcon("C:\\Users\\Administrator\\Desktop\\3.jpg").getImage();
g.drawImage(image, 10, 20, this);

}
}
}

Answer 1

你的这条语句public void paintComponet(Graphics g)中的函数名paintComponet拼错了
应该是paintComponent 即Componet少了个字母'n' Component
函数名改成paintComponent就行了.

Answer 2

image要先加载好 。。。。。。。。。。。。。
