Java ImageIcon lan tangan bengkok

import javax.swing.*;
import java.awt.*;

public class TEST {
    public static void main(String[] args) {
        new Window();
    }

    static class Window extends JFrame {
        Window() {
            setSize(300, 250);
            setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
            setLayout(new FlowLayout());

            ImageIcon icon = new ImageIcon("icon.jpg");

            setIconImage(icon.getImage());
            getContentPane().add(new JLabel(icon));

            setLocationRelativeTo(null);
            setVisible(true);
        }
    }
}

Ana kode kaya ngapa gambar ora ditampilake ing jendhela lan apa lambang jendhela ora diselehake. icon.jpg wis ukuran 32x32 piksel lan ing src karo liyane saka file (Aku nggunakake intellij idea). Asil eksekusi kode kasebut minangka jendhela kosong kanthi lambang standar.
