向JLabel添加ImageIcon

Question

My program will run, and a button will appear, but the image which is in the res folder that is in a referenced library will not appear ( egg.png ). There are no errors, but I'm confused as to why it won't run properly.

package gui;

import javax.swing.Icon;
import javax.swing.ImageIcon;
import javax.swing.JButton;
import javax.swing.JFrame;

public class IconButton {
public static void main(String args[]) {
    JFrame frame = new JFrame("DefaultButton");

    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    ImageIcon image = new ImageIcon("C:\\Users\\Jack Young\\Desktop\\Egg game Sprites");
    JButton button = new JButton();
    button.setIcon(image);
    frame.add(button);
    frame.setSize(300, 200);
    frame.setResizable(false);
    frame.setVisible(true);
  }
}

Answer 1

try this:- for eg:- if image is in icons folder in resource:-

private final ImageIcon imageIcon = new ImageIcon(getClass().getClassLoader().getResource("icons/image.png"));
