Java adding ImageIcon to JLabel

问题

I am trying to make a very basic game with Java and I am having trouble displaying an image on a JFrame. It has worked in the past for me and now is not, i can't see what I did wrong.

I have tried printing the current working directory and changing where I get my image to match that. It is likely that the problem is not getting the image, since my (filefinder or filereader or something like that) can find it without problems, but I cannot correctly add it (the ImageIcon) to the JLabel, or that to the JFrame.

This is my code...

JFrame frame = new JFrame("no image");
ImageIcon image = new ImageIcon("C:/Documents and Settings/user/Desktop/hi/xD/JavaApplication2/image.png");
JLabel imagelabel = new JLabel(image);
frame.add(imagelabel);

The JFrame has been setVisible(true) and pack().

Could someone please help me understand what is wrong.

回答1:

Your problem lies here:

   ImageIcon image = new ImageIcon("C:/Documents and Settings/user/Desktop/hi/xD/JavaApplication2/image.png");
   JLabel imagelabel = new JLabel(character);

You create an ImageIcon "image" but you create your JLabel with "character".

It should be:

JLabel imagelabel = new JLabel(image);

Try,

ImageIcon image = new ImageIcon("c:\\path\\image.png");
imagelabel = new JLabel(character, image, JLabel.CENTER);
frame.add(imagelabel);

//class name image 
class image { 
    image() 
    //constructor { 
        Frame f=new Frame("Image"); 
        //Frame
        f.setSize(500,500); 
        f.setVisible(true); 
        Panel p =new Panel(); 
        //Panel 
        f.add(p); 
        p.addLayout(null); 
        ImageIcon ii=new ImageIcon("set your image path"); 
        //ImageIcon is used to image Display . 
        Label l =new Label(ii); 
        p.add(ii); 
        p.setBounds(set you bounds); 
        //Like that(20,20,500,40); 
    } 

    public static void main(String [] args) { 
        image obj = new 
    } 
}
