使用单独的 ImageIcon 创建多个 JToggleButton

Question

    ImageIcon img_1 = new ImageIcon("src/menu/btn_1.jpg");
    ImageIcon img_2 = new ImageIcon("src/menu/btn_2.jpg");
    ImageIcon img_3 = new ImageIcon("src/menu/btn_3.jpg");
    ImageIcon img_4 = new ImageIcon("src/menu/btn_4.jpg");
    ImageIcon img_5 = new ImageIcon("src/menu/btn_5.jpg");
    ImageIcon img_6 = new ImageIcon("src/menu/btn_6.jpg");
    ImageIcon img_7 = new ImageIcon("src/menu/btn_7.jpg");
    ImageIcon img_8 = new ImageIcon("src/menu/btn_8.jpg");
    ImageIcon img_9 = new ImageIcon("src/menu/btn_9.jpg");

    bgNumbers = new ButtonGroup();
    btnNumbers = new JToggleButton[9];
    for (int i = 0; i < 9; i++) {
        btnNumbers[i] = new JToggleButton(???);
         .....
         .....
    }

如何将个人 ImageIcon img_1、img_2 ...... img_9 插入循环？
