Java で画像を使用して JPanel の背景を簡単にカスタマイズする方法

<code class="java">public static JPanel drawGamePanel() {
    //Create game panel and attributes
    JPanel gamePanel = new JPanel();
    Image background = Toolkit.getDefaultToolkit().createImage("Background.png");

    //Override the paintComponent method to add background image
    gamePanel.paintComponent(new Graphics() {
        @Override
        public void drawImage(Image img, int x, int y, ImageObserver observer) {
            super.drawImage(img, x, y, observer);  // Draw the game panel's contents
            super.drawImage(background, 0, 0, observer);  // Draw the background image
        }
    });

    //Set Return
    return gamePanel;
}</code>

<code class="java">JPanel gamePanel = new JPanel();

ImageIcon backgroundIcon = new ImageIcon("Background.png");
JLabel backgroundLabel = new JLabel(backgroundIcon);

gamePanel.add(backgroundLabel);</code>
